用稻壳合成氮化硅超微粉的反应动力学特性

The character of reaction kinetics for producing ultra fine Si_3N_4 powder with rice husks

对用稻壳合成氨化硅超微粉过程中的氮化反应动力学特性进行了研究。结果表明：在以氨气为氮化气源的体系中，合成氨化硅粉的氮化反应活化能为１０３ｋＪ／ｍｏｌ。

In this peper,we have researched into the character of reaction kinetics for producing ultra fine Si3N4 powder withrice husks. And it has ben shown that the activation energy of nitriding reaction, in which the nitridins gas is NH3, is103kJ/mol.
