A possibility in tailoring microstructures and properties of silicon nitride ceramics is demonstrated by the use of fine .beta.-Si3N4 powders. Fine powders were produced by plasma-chem. synthesis and by crystn. of amorphous Si3N4 in the presence of a

Nanosized silicon carbonitridepowders have been synthesized by gasphase pyrolysis of evaporable precursors at temperatures between 600 and 1000 deg C.These synthesis have been carried out by using of mixtures of cyclic polysilazanes,which were prepar

The influence of additions of MoSi2 on the microstructure and the mechanical properties of a silicon nitride material with Nd2O3 and AlN as sintering aids was studied. The composites containing 5, 10 and 17.6 wt per cent MoSi2 were fabricated by hot

Dense Si3N4-TiN-composites with 20 - 50 wt-percent TiN with various grain sizes were produced by hot pressing and gas-pressure sintering under nitrogen gas atmosphere. The dependence of the densification behaviour on the TiN-content and on the grain
