AlSiC - Wikipedia

AlSiC, pronounced "alsick", is a metal matrix composite consisting of aluminium matrix with silicon carbide particles. It has high thermal conductivity (180–200 W/m K), and its thermal expansion can be adjusted to match other materials, e.g. silicon and gallium arsenide chips and various ceramics..

Densifiion of nanostructured ferric alloy steel (NFA) and silicon carbide (SiC) composites with various compositions has been conducted by spark plasma sintering. The oxidation mechanism and corrosion resistance under water vapor condition at elevated temperature is under investigation.

Low Ster Surfaces on Silicon Carbide - ASTM …

Reaction bonded silicon carbide (RB SiC) can be readily fabried to near net shape and mirror blanks produced by this method can potentially be less costly than those fabried by chemical vapor deposition (CVD). However, RB SiC is two phase, SiC and up to

Fiber Reinforced Ceramics | SGL Carbon

Fiber reinforced ceramics are manufactured by infiltrating porous carbon fiber reinforced carbon components with liquid silicon. The material properties can be customized to your appliion by the amount and type of carbon fibers (milled fibers, short or long fibers) which are implemented into the ceramic SiC matrix.

Silicon carbide sintering - FUENTES; RICARDO I.
