SiC/Si 3 N 4 nanocomposites were prepared with carbon black and β£-Si 3 N 4 powders by hot-pressed method. The microstructure, phase composition, dielectric and mechanical properties of the nanocomposites were investigated. The relative densities of SiC/Si 3 N 4 nanocomposites decreased from 99 to 86

In the presented work some properties of a recently developed Si 3 N 4 /SiC micro/nanocomposite have been investigated. The material was tested using a pin on disc configuration. Under unlubricated sliding conditions using Si 3 N 4 pin at 50 % humidity, the friction coefficient was in the range of 0
Sample controlled reaction temperature (SCRT) has been used for the first time to study the kinetics of the carbothermal reduction of silica in nitrogen to obtain silicon nitride (Si 3 N 4 ). It is noteworthy to point out that SCRT method allows both a good control of pressure in the sample surroun
