Background
Titanium silicocarbide (Ti3SiC2) is also sometimes called titanium silicon carbide.
It is a unique ceramic in that it possesses ceramic and metallic characteristics meaning that it is suited to both mechanical and electrical applications. For example it exhibits high temperature stability as well as high electrical and thermal conductivities as well as having a moderate resistance to oxidation.
Furthermore, it has a high fracture toughness at high temperatures and can be machined using hardened steel tools.
