Prediction and Verification of Thermodynamic Functions of Compounds in Si-Al-O-N System

摘要

A computer program has been composed and the Gibbs free energy of some compounds in Si-Al-O-N system is assessed and predicted according to the quasi-paraboloid rule. It makes the chemical design of the sialon materials possible. As an example, the thermodynamic calculation and verification for BN-o′-sialon composite is made.
