Indirect selective laser sintered (SLS) silicon carbide objects have been successfully infiltrated with silicon. Selective laser sintering has several advantages over conventional manufacturing methods of silicon carbide parts including more greater geometrical freedom, lower process temperatures and pressures, cheaper starting materials, and higher geometrical tolerances.
Recrystallized silicon carbide (RSIC) is a pure silicon carbide material with approximately 11 to 15 % open porosity. This material is sintered at very high temperatures from 2,300 to 2,500° C, at which a mixture of extremely fine and coarse grains is converted to a compact SiC matrix without shrinkage.
silicon carbide ceramics is the best choice of heat exchanging appliion in the extream environment. silicon carbide is a single phase,presureless sintered silicon carbid which has high purity, fine grain and low porosity and etc. This silicon carbide ceramics heat

For example, sintered silicon carbide retains its strength at elevated temperatures and shows excellent time-dependent properties such as creep and slow crack growth resistance. In contrast, reaction-bonded SiC, because of the presence of free silicon in its microstructure, exhibits slightly inferior elevated temperature properties. 7
Global silicon carbide ceramics market is segmented into type, appliion, end-use industry, and region. Based on type, the market is divided into CVD silicon carbide, recrystallized silicon carbide, hot pressing silicon carbide, reaction bonded silicon carbide, direct sintered silicon carbide, and others such as silicon nitride-silicon carbide and pressure sintered silicon carbide.

1 · Silicon carbide (SiC) ceramic is an ideal material for mechanical seal because of its super hardness, high strength, low friction coefficient, good thermal conductivity, and resistance to friction and wear. However, due to relatively high resistivity of SiC ceramic, the triboelectric charge caused by rubbing of mechanical seal end-faces could not be released. It is terrible that the
