  • Method for producing a ceramic
    Patent number: 4988646
    Abstract: A nitride, preferably AlN, ceramic is produced by contacting a mixed oxide gel (produced from organometallic/inorganic metal salt precursors) which, during sintering steps, transform into a melt that forms low contact angle with the nitride powder. The composition is sintered to thereby produce the desired ceramic.
