Preparation of TiC Crystals from High Temperature Solutions and Their Characterisation

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 Al₂O₃ 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.

Keywords: Titanium carbide crystals, crystallisation, morphology, high temperature solutions
