Abstract The results of obtaining TiC x crystals by the HTS method with application of Co and Ni as high‐temperature solvents are presented. The starting materials were melted in Al 2 O 3 crucibles induction heated up to 1700°C. The obtained specimens were studied by means of optical interference microscopy, electron microscopy and X‐ray microanalysis. It was that during slow cooling of the melted Co‐Ti‐C and Ni‐Ti‐C solutions, TiC x crystallise as primary crystals and on reaching the eutectic temperature for the quasi‐binary systems crstallisation of Co‐TiC x and Ni‐TiC x took place. The obtained crystals were of cubic form and had a maximum size of 1 mm.
