Carbothermal nitridation process of mechanically

2013-8-1  According to Romero et al. the main problems of the carbothermal nitridation process are the particle size of the reactants and the need for a close contact between them. In an attempt to avoid these problems, ball-milled carbon was used as a starting reactant. The carbon used here had undergone ball milling treatment for five hours.

Influence of the experimental conditions and the

Abstract Silicon nitride has been obtained by carbothermal nitridation of silica using Constant Rate Thermal Analysis (CRTA) method. This method permits to maintain the CO concentration generated in the reaction in a constant value previously selected by the user. The results obtained have shown that the synthesis of α-Si 3 N 4 is improved by increasing the partial pressure of CO in the
