Reaction‐Rate‐Limiting Steps in Carbothermal Reduction Processes
Journal of the American Ceramic Society, 1985The production of β‐sialon (Si3A1303N5) and nonoxidic powders by carbothermal reduction of oxides is discussed. Special attention is paid to the rate‐determining steps in the conversion process performed in a packed‐bed reactor.

Carbothermal reduction synthesis of TiB2 ultrafine powders
Ceramics International, 2016Abstract Submicrometric TiB 2 powders were synthesized by carbothermal reduction process using titanium dioxide, boron carbide and carbon black as the starting materials. The influence of different amount of boron carbide (22.0–26.8 wt%), calcination temperature (1400–1900 °C) and holding time (15–90 min) on the composition and microstructure of the
