The constant evolution of material science and technology challenges existing material characterization methods. The purpose of material characterization is to prove a material's structure and properties. It is a fundamental process in material science involving studying the interaction of electrons, photons, ions, atoms, strong electric fields, and thermal energy to measure the physical and chemical properties of materials. Alfa Chemistry offers a wide variety of techniques including Microscopy, Spectroscopy, and Macroscopic characterizations that help to understand different materials. The energy spectra, fluoresce spectra, and mass spectra can be obtained, reflecting the electrons, photons, ions, atoms, and molecules information. Surface composition, surface structure, surface electronic states, and surface physicochemical processes can be collectively measured as part of advanced material characterization. Numerous analytical techniques are available at Alfa Chemistry such as: atomic force microscopy (AFM), scanning electron microscopy mounted with an Energy dispersive X-ray spectrometer (SEM/EDS), transmission electron microscopy mounted with an energy dispersive X-ray spectrometer (TEM/EDS), X-ray diffractometer (XRD), raman spectroscopy, thermo gravimetric analyzer (TGA) and differential scanning calorimetry (DSC), etc.
We can help you reach optimal yields and consistent performance whether you are using conventional manufacturing techniques or advanced processing technologies. We work with a wide range of materials including:
Nanomaterials can be generally defined as a material having particles or constituents of nanoscale dimensions, or one that is produced by nanotechnology. Analyzing nanomaterials offer insight into the mechanisms that govern material interactions at the micro and nanoscale. We have experiences with nanoparticle imaging, elemental mapping, crystallinity studies, as well as component analysis. Check our instruments list to see our capability.
Metals are the most applied materials in modern industry. Metal testing mainly focuses on metal components/structures, synthesis/processing, properties, and service performance. Metallurgical analysis reveals the condition and makeup of your materials with macro, micro and SEM examinations. These analyses reveal microstructure, processes performed on the material during manufacture and whether or not the materials meet the required specification(s) to ensure durability in the intended use. We offer microscopy evaluation, fracture, hardness, thermal spray coating analysis, weld qualification, identification studies, etc.
The testing and characterization of thin film materials are critical to the application of materials. Characterization of film structures and properties relies on test equipment and methods. The characterization parameters of thin film materials usually include the thickness of the thin film, which is usually measured using the probe method (AFM); the morphology of the thin film can be tested using scanning tunneling microscope; the composition of the thin film is mainly used in the X-ray electron energy spectrum; the stress characterization of the thin film can be measured using indirectly deformation method and other measurements. SEM, TEM, AFM, XRD, XPS have all been involved in the thin films characterizations.
From corrosion-resistant smart coatings to new high-pressure/high-temperature materials, coatings have been applied to many aspects in our lives. We offer some of the most innovative test methods in materials science from functional nano-coating materials to sustainable biological coatings.
Materials in general, can be categorized as Metals, Organics (Plastics), Ceramics and Composites. Materials might be degraded by chemicals, heat, moisture, radiation, enzymatic action, mechanical wear, fatigue, creep, age etc. Ceramics are generally considered more stable materials than others. We characterize raw materials, processed, mechanical and other properties of conventional and advanced ceramic materials including microstructure, mechanical properties, thermal properties, particle size, chemical composition, and behavior in different media studies.
A composite material is normally made from two or more materials that can give superior properties compared to the individual constitutes. Without dissolving or blending each individual compound, the individual components can remain separate and distinct within the finished composite. Composite materials can offer modulus/vibration damping increases, tensile strength/ compression strength/interlaminar shear strength enhancement as well as improve fracture toughness. The constituents of composites are mainly matrix, reinforcing material and coupling agent. Mechanical properties of composites include tensile strength, compressive strength, bending strength, shear strength, hardness and fatigue. With professional knowledge of various types of composites, as well as an understanding of their behaviors on the characteristics/relative amounts/geometry/distribution and properties of the constituent phases, scientists and engineers at Alfa Chemistry we can provide many testing services about composite materials.
An integrated circuit is defined as a set of electronic circuits on one small flat piece of semiconductor material, normally silicon. A functional electronic circuit requires transistors, resistors, diodes, and the connections between them. Through the manufacturing process of oxidation, photolithography, diffusion, epitaxy and aluminum vapor, the electronic components can be put together, fabricated on a small piece or a few small pieces of semiconductor wafer or dielectric substrate and then packaged in a package to become an integrated circuit. We can provide professional instruments and inspections for many industries, including CD-SEM, design review SEM, wafer surface inspection system and dark field wafer defect inspection system, to meet the demand of our customers. The test comprises applying signals to each input pin of the circuit at predetermined timings and in detecting output signals at the output pins of the circuit at predetermined timings. For different test methods, we provide IEEE 488 standard and IEEE 1014 standard for automated testing, IEEE 1149.1 standard for digital testing, P1149.4 standard for mixed-signal testing and RF testing.
Aluminum and its alloy possess many excellent properties, such as high specific heat, no magnetism and low temperature brittleness. The surface of aluminum can spontaneously form a natural oxide film (2.5-5nm) in the air, which has good corrosion resistance in the general natural environment. However, this oxide film is amorphous. Therefore, the structure is loose, thin, porous and low mechanical strength. In some extreme environment, such as in the ocean, acid and base, the corrosion resistance is poor.
Aluminum anodization is a process technology, in which aluminum or aluminum alloy product is the anode. Putting the anode in electrolyte solution for electric processing, makes its surface form oxide film. After aluminum anodization treatment, the products are called anodic aluminum oxide (AAO). Compared to natural aluminum oxide film, this treated oxide film performs excellent corrosion and abrasive resistance. Through various process controls coil anodizers are able to monitor and control the correct anodized coating for your application. The pre-anodized aluminum coil can be used in nearly all fabricating operations with exceptions of deep drawing and extrude.
Liquid crystals are matter in a state which has properties between those of conventional liquids and those of solid crystals. Liquid crystal is partially ordered and anisotropic. In terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order. Recently, new directions for applied and fundamental liquid crystal science gradually becoming the interest of scientists. The new directions mainly include liquid crystals for organic electronics and energy conversion applications, liquid crystal templating for creating nanostructured materials or ordering nano- and microparticles, composite materials containing thermotropic liquid crystals as functional additive, actuators made from liquid crystal elastomers and liquid crystals in biology, biotechnology, food science and pharmacology. We provide a full range of chemical/physical property studies including splay and bend elastic constants, threshold voltage, and dielectric constants for both positive and negative anisotropic nematic liquid crystal materials. The morphology, shape, chemical composition of nano-size liquid crystal can be measured using SEM, TEM, AFM, XRD, etc.
There are many types of batteries such as normal battery that are used in our daily appliances, and photovoltaics. Photovoltaics (PV) is a device that can realize the conversion of light into electricity, which can provide power electrical devices such as flashlights, smartphones and electric cars. While inside the photovoltaics, semiconductor materials are the most common materials, and they have an electrical conductivity value falling between that of a conductor and an insulator. Besides photovoltaics, a wafer, also called a slice or substrate, is a thin slice of semiconductor material, such as a crystalline silicon. It is used in photovoltaics for conventional, wafer-based solar cells. Furthermore, silicon wafer is very important in semiconductor industry. Thanks to silicon wafer, computers and mobile phones have emerged. It can be said that without good silicon wafer, there is no development of the semiconductor industry. We photovoltaics, semiconductor, wafer & battery testing such as: battery life & capacity, compositions, as well as the elements analysis, resistivity of battery, charge and discharge times of rechargeable batteries, carbon and oxygen content of silicon wafer, center thickness of silicon wafer, saw mark, BOW, warp and edge defects detection of silicon wafer, etc.
Plastic/polymer/rubber is widely used in almost every industry such as aerospace, automotive, consumer packaging, medical device and so on. There are several scenarios when manufactures need to characterize the polymer products, such as routinely QA/QC, R & D for developing new products/ improve performance/reduce cost, contamination identification, as well as competitor products analysis. Polymer Testing provides a forum for developments in the testing of polymers and polymeric products and is hence of interest to those concerned with testing rubbers and plastics in research, in production and in connection with the specification and purchase of products.
