Silicon Carbide (SiC) | Morgan Technical Ceramics

The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles. Sintered SiC is produced from pure SiC powder with non-oxide sintering aids. Conventional ceramic forming processes are used and the material is sintered in an inert atmosphere at temperatures up to 2000ºC or higher.

Abstract: A method for the growth of a SiC single crystal comprisingintroducing a seed crystal of SiC single crystal having an exposed face deviating from the {0001} plane by an angle .alpha..sub.1 of about 60.degree. to about 120.degree., typically about 90.degree. and SiC powder as a raw material into a graphite crucible,elevating the temperature of the SiC powder in an atmosphere of inert

Pure CVD silicon carbide wafer carriers | Engineer Live

The pure CVD SiC wafer carriers significantly outperform traditional wafer carriers used in this process, which are graphite and coated with a layer of CVD SiC. These coated graphite-based carriers cannot withstand the high temperatures (1100 to 1200 degrees C) required in GaN deposition for today’s high brightness blue and white LEDs.

A new technological step for sic mirrors preparing OTOS

The mirrors optical face is generally clad with a fully pore-free SiC CVD layer, a few hundred micrometers thick, thus minimizing stering and its contribution to stray light. For OTOS, AIRBUS Defence & Space has designed and is developing a new concept of primary mirror based on Boostec ® SiC technology.

Trex Enterprises Corporation (Trex) Telescope System Capabilities

The CVC SiC process utilizes the same chemical vapor deposit technique as CVD to form in situ silicon carbide; however, a secondary phase such as powder is added to the high purity reactant gas stream to produce the composite structure.
