In the paper, scientists used a new technology and synthesized carbide from titanium, zirconium, niobium, hafnium, and tantalum (TiZrNbHfTaС 5), as well as carbonitride from these components.

Diborides and carbides of transition metal elements, including zirconium (Zr), hafnium (Hf), and tantalum ... and good thermal conductivity, while carbide UHTCs show higher melting temperatures ...
