Abstract

Abstract

Si₃N₄ powders made from imide process and thermal decomposed at different temperatures have investigated by XPS surface analysis; They were compared with a commercial Si₃N₄ powder made with nitridation process. Oxygen both in combined form of Si_2.2-2.7N_2.9-3.7O layer and absorbed form were found on the powder surface, in contrast to Si_0.8 N_0.8O layer and absorbed form in the case of Si₃N₄ powders made from Si aitridation.
