Ceramic Matrix Composite Based on Silicon Nitride or Aluminium Nitride

The melting, casting, forging or evaporation of the high purity alloys requires withstanding corrosion, adhesion and thermal shock. Detailed scientific results are represented for the development of high performance composite ceramics such as reaction bonded SiAlON/sinter - alumina/graphite, Si3N4/BN and AlN/TiN/BN using differnt starting mixtures and technological treatments such as nitriding, pressure less sintering or hot pressing.
