can be observed that the silicon carbide was sintered to about 0.93 of its relative density by using alumina and yttria as sintering additives. This finding was as a result of a eutectic liquid formed between alumina and yttria at sintering temperature of 1930 C.
Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3N 4 is the most thermodynamically stable of the silicon nitrides. Hence, Si 3N 4 is the most commercially important of the silicon nitrides when referring to the term "silicon nitride". It is a white, high-melting-point solid that is relatively chemically inert
This study aims to form lubriive carbon layers on the surfaces of sintered plates and thin films of silicon carbide (SiC) by local laser irradiation. This technique is suitable for use with micro-device appliions on which it is difficult to add a lubriive agent. The proposed method is based on silicon elimination from SiC, which is referred to as the carbide derived carbon process
