Tantalum carbide TaC
|
| An extremely hard refractory ceramic material, commercially used in tool bits for cutting tools. It is usually processed by sintering. It has the appearance of a brown heavy powder. It is sometimes used as a fine-crystalline additive to tungsten carbide alloys. It is an important cermet material. |
| Tantalum carbide-graphite, a composite material developed in Los Alamos National Laboratory, is one of the hardest materials ever synthesized. |
Tantalum nitride TaN
|
| It is used to create barrier layers between copper and silicon in the manufacture of integrated circuits, to create thin film surface mount resistors as well as other electronic applications. |
