| Abstract: | The effect of O2, SiO, CO gas partial pressures and temperatures at certain N2 partial perssure on the phase stability of the SiO2-C-N2 system was studied. The phase stability diagrams in equilibrium were constructed, which can guide the synthesis processing conditions of the pure Si3N4 powder in the method of carbothermal reduction and nitridation from SiO2. |
