Hafnium carbonide (HfC), a grayish, black powder, has a face-centered cubic shape. It has a high melting value (3890), which is why it is an excellent material to use as a lining for metal melting crucibles. Hafnium carbonide has a high elastic coefficient, low thermal conductivity, and good impact resistance. This makes it a good…

Hafnium carbonide, a gray-black powder has a square-shaped structure with an extremely high melting temperature of 3890. It has a very high melting point and can be used to line metal melting vessels with high melting points. Hafnium carbid has an excellent elastic coefficient and high electrical and/or thermal conductivity. Also, it’s a good choice…
