The Research On Preparation Of β-SiAlON Ceramics And Its Porous Material

Porous ceramics has high porosity, small density, high specific surface,and high temperature resistance, corrosion resistance,β-SiAlON has excellent mechanical property, and excellent oxidation resistance The instantaneous liquid phase sintering ofβ-SiAlON can efficacious reduced the temperature of sintering. In this paper, the porous ceramics were prepared withβ-SiAlON.β-SiAlON is commenly described by fomula Si6-zAlzOzN8-z(0
