Gas pressure sintering of β-silicon nitride

The sintering behaviour of beta-Si3N4 powder was investigated in 980 kPa (10 atm) nitrogen at 1800-2000 C. It is shown that beta-Si3N4 has a higher sinterability than the finer alpha-Si3N4. The solution of small grains and reprecipitation on large grains occurred during sintering at greater than 160...
