Useful:

• Uses: A mixture of tantalum carbide (TaC) and graphite is a very hard material and is used to form the cutting edge of machine tools. Tantalum monocarbide, TaC, is a gold-colored powder produced industrially by direct reaction of carbon with either tantalum scrap or tantalum pentoxide at temperatures up to 1,900 °C (3,452 °F). It is added in small amounts (0.2–2 wt %) in the form of TaC or mixed carbides like TaNbC and WTiTaC to tungsten carbide–cobalt-based cutting tools in order to reduce grain growth. Adding 2–15 wt % TaC to cemented carbides considerably increases their thermal shock resistance and their resistance to cratering and oxidation. The tantalum–carbon phase diagram shows the existence of several subcarbides. Cutting tools and dies, cemented carbide tools.
