Application
Tantalum Carbide Powder is a hard, heavy, refractory, crystalline solid known for its remarkable hardness of 1800 kg/sq mm and its resistivity of 30 μΩ?cm at room temperature. This gold-colored powder is primarily produced through the direct reaction of carbon with tantalum scrap or tantalum pentoxide at temperatures reaching up to 1,900°C (3,452°F). Tantalum Carbide Powder is used to enhance the performance of cutting tools and dies, often forming the cutting edge of machine tools when combined with graphite. In small amounts, it improves the stability and performance of tungsten carbide-cobalt-based cutting tools by reducing grain growth. When added in quantities ranging from 2-15 wt %, it significantly boosts the thermal shock resistance, cratering, and oxidation resistance of cemented carbides. This material's exceptional resistance to chemical action, except at elevated temperatures, makes it ideal for applications requiring a combination of corrosion and wear resistance, contributing to its use in nozzles, orifice plates, and valve components.
