Optimization of Gas Composition Used in Plasma …

In recent years, reaction-sintered silicon carbide (RS-SiC) has been of interest in many engineering fields because of its excellent properties, such as its light weight, high rigidity, high heat conductance and low coefficient of thermal expansion. However, RS-SiC is difficult to machine owing to its high hardness and chemical inertness and because it contains multiple components. To overcome

Joining of Dense Silicon Carbide Containing Free Silicon …

The sintered body had a bulk density of 3.06g/cm 3 and 4-point bending strength of 53kg/mm 2 (520MN/m 2). Since about 10wt% of free Si contained in the reaction-sintered SiC evaporates above 1400°C, especially in vacuum, it is to be noted that the sintered body is obtainable by siliconizing from 1400°C to 1450°C, lower than the conventional technique.

Nearly fully dense carbides of zirconium, hafnium, and tantalum were obtained by pressureless sintering at 1950°C with the addition of 5–20 vol% of MoSi2. Increasing the amount of sintering aid, the final density increased too, thanks to the formation of small amounts of liquid phase constituted by M-Mo-Si-O-C, where M is either Zr, Hf, or Ta. The matrices
