Abstract
Mechanochemical preparation of nanoscale hafnium (IV) carbide was explored. It was demonstrated that the Hf/C mechanocomposite with a wide particle-size distribution was formed in the first step. Fused hafnium (IV) carbide was produced from nanoscale hafnium (IV) carbide and the hafnium/carbon mechanocomposite by treatment with high-intensity photon flux. According to research results, the mechanocomposite is more preferable and may be used as a precursor to make products of fused hafnium (IV) carbide using additive technologies.
