Studies of pressureless sintering of Si3N 4 based matrices and Si3N4-SiC composites in the Y-Si-A1-O-N and Hf-Y-Si-A1-O-N additive systems have been carried out. Mechanical testing indicated that matrices had higher hardness and higher flexural strength than composites. Composites had higher fractur

Si 3 N 4 /SiC composite ceramics were sintered in order to investigate their bending strength behavior after crack-healing. Y 2 O 3 and TiO 2 powder was added as sintering additives to enhance it's sintering property. A three-point bending specimen was cut out from sintered plates. About 100 m semi-

Aminoboranes, pure or partially converted into aminoborazines using thermal or aminolysis polymerization, have been used as boron nitride precursors. An amorphous BN preceramic is obtained when pyrolysed up to 1000Β°C that can be stabilized using further annealing up to 1400Β°C or crystallized into h-
