Process for producing a translucent beta -sialon sintered product |
摘要 |
A process for producing a translucent beta -sialon sintered product, which comprises mixing fine powders of silicon nitride and aluminum nitride having a high purity of at least 99% and a particle size of at most 200 microns and fine powders of aluminum oxide and silicon oxide having a high purity of at least 99% in such a proportion as to form beta -sialon of the formula Si6-zAlzOzN8-z where z is from 1 to 4.2, and hot-pressing the mixture in a nitrogen atmosphere at a temperature of from 1500 DEG to 1850 DEG C. under pressure of from 10 to 1500 kg/cm2.
