Boostec® silicon carbide -SiC- for scientific instrumentation and industrial equipment Mersen Boostec is specialized in the development of innovative products in sintered silicon carbide. For some appliions, the silicon carbide can receive a CVD (chemical vapor deposition) coating to give a completely non-porous high-purity SiC surface.
The process of preparing silicon carbide by reaction sintering is to prepare proper amount of carbon-containing material in silicon carbide powder, and to synthesize new silicon carbide by reacting carbon with residual silicon in silicon carbide powder at high
Pressureless silver (Ag) sintering was optimized at 250 C in vacuum and nitrogen gas atmosphere with silicon carbide (SiC) chips, and silicon nitride active metal-brazed substrates (A). A 1200-V/200-A power module was developed using a pressureless Ag-sintered live SiC metal-oxide-semiconductor field-effect transistor (MOSFET) device and a Si 3 N 4 A substrate module, and diverse
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

Self-sintered silicon carbide carries a slight price premium compared to the reaction bonded version. Although the preferred seal face material, it often is too brittle for some seal face designs. It is one of the most popular materials used in mechanical seal face design and is recommended in high temperature water or hot oil appliions because of its excellent thermal conductivity.
Silicon Carbide based Nitride Bonded Silicon Carbides (NBSIC) are used for their good thermal, mechanical and wear resistance attributes. Although heating at high temperature and pressure can produce sintered pure silicon carbide, the process commercially viable.
All three substances will decrease the electrical conductivity of a silicon carbide product. In general, however, silicon carbide has a purity of over 99.9995%. The three most commonly produced commercial grades of silicon carbide are sintered silicon carbide
Silicon Carbide is among the hardest of ceramics, and retains hardness and strength at elevated temperatures, which translates into among the best wear resistance also. Additionally, SiC has a high thermal conductivity, especially in the CVD (chemical vapor deposition) grade, which aids in thermal shock resistance.
Silicon carbide has been the most widely used material for the use of structural ceramics. Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at temperatures up to 1650 ° C, have led to a wide range of uses.
