摘要:
Oxidation of alpha -silicon nitride in air with a water vapor pressure of 2 multiplied by 10** minus **2 atm in the temperature range 1100-1450 degree C is controlled by the diffusion of oxygen through silica. The oxidation data can be best represented by two sets of curves, one for the temperature range 1144-1230 degree C and the other for 1378-1450 degree C. The activation energy oxidation is 70. 15 kcal/mole.
