High Pressure Sintering of Non-Qxide Materials

Journal of the Japan Society of Powder and Powder Metallurgy, 1978
Pure materials of AIN, alpha-Si3N4 and TiC, without additives were sintered at 800 C to 1400 C under the pressures of 30 kbar and 50 kbar for 0.5 hours. The maximum density of sintered bodies for the cited materials was nearly 100% for AIN, 98% for TiC and 96% for alpha-Si3N4.
