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

Аннотация

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 the synthesis products. The synthesized powders were boron carbide crystals ìm in size and nanoparticles.
