Publikováno v: Refractories and Industrial Ceramics. 59:528-533

The heterogeneous CaB6–TiB2 powder mixtures were synthesized by reducing the mixture of TiO2 and CaCO3 with boron carbide in vacuum at 1400 – 1650°C. Reaction hot pressing was conducted according to the following regime: 1500°C (synthesis in va

Combined Carbothermal Synthesis of Powders in the B4C–SiC–TiB2 System

Autor: D. P. Danilovich, T. V. Kotsar, S. V. Vikhman, S. S. Ordan’yan

Publikováno v: Refractories and Industrial Ceramics. 58:174-178

A mixture of boric acid, silicon dioxide, and titanium dioxide powders in the eutectic ratio was reduced by carbon (as soot) at 1600°C in vacuo in order to produce phases in the B4C–SiC–TiB2 system. Only the expected phases were identified in th
