Tantalhafniumcarbid ( Ta4HfC5 ) is a chemical compound consisting of tantalum, hafnium, and carbon. It is an extremely hard non-oxide ceramics. It has one of the highest known melting points of 4488 K ( 4215 ° C). Only tantalum in the form TaC0, 89 has a similar high melting point ( 4000 ° C). It is also the only known material that you can not weld or cut with a torch Langmuir ( Arcatom welding). In his appearance as well as chemical and physical properties of tantalum carbide and hafnium carbide, it is similar to.
