Abstract
The 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. It is shown that powders with specific surface area >10 m2/g can be produced by the correct choice of pellet size, gas flow rate, temperature, and raw material.Keywords
