应用
Tantalum carbides? is used in ? tungsten carbide. It is also used as a coating for steel moulds in the injection moulding of aluminum alloys. While providing a hard, wear resistant surface, it also provides a low friction mould surface. It is also used in the production of sharp instruments with extreme mechanical resistance and hardness, tool bits for cutting? tools.

备注
Store in cool, dry place in tightly closed container.
