A Novel Processing Route for Fabricating One-Dimension Elongated Ca α-Sialon Crystalline Powders

Abstract

A novel process route was developed for fabricating Ca -sialon crystalline powders in the present work. Loose powders with an average diameter of about 0.5 µm and an average length of about 5 µm were obtained by combustion synthesis process, followed by ultrasonic dispersion in acid to dissolve the liquid phase and obtain loose powders. The phase formation was detected by XRD. The particle morphology was observed by SEM.
