TaC coating graphite is created by coating the surface of a high-purity graphite substrate with a fine layer of tantalum carbide by a proprietary Chemical Vapor Deposition (CVD) process.
Tantalum carbide (TaC) is a compound that consists of tantalum and carbon. It has metallic electrical conductivity and an exceptionally high melting point, making it a refractory ceramic material known for its strength, hardness, and heat and wear resistance. The melting point of Tantalum Carbides peaks at about 3880°C depending on purity and has one of the highest melting points among the binary compounds. This makes it an attractive alternative when higher temperature demands exceed performance capabilities used in compound semiconductors epitaxial processes such as MOCVD and LPE.
