CERAMIC DEPOSITING VESSEL HAVING IMPROVED STRENGTH AND ELECTRICAL PHYSICAL PROPERTYFOR ITS PRODUCTION

摘要

The invention provides a TiB2-BN-AIN type ceramics deposited vessel. Its formula is wTiB2-xBN-yAIN-zWC in which w, x, y and z are 0.6 to 0.7, 0.15 to 0.20, 0.08 to 0.17 and 0.03 to 0.15 (w+x+y+z=1). The characteristics of process for producing the vessel are mixing TiB2-BN-AIN type ceramics material with WC, a sintering additive and sintering the mixture at a temperature of 1800-1950 C under a pressure in nitrogen atmosphere
