Know More about the Manufacture and Application of Silicon Carbide (Sic)

Silicon carbide (SiC) also called carborundum is a compound formed of silicon and carbon having the chemical formula of SiC. Naturally it is found in rare mineral rare mineral named moissanite. Silicon carbide powder was earlier used as abrasive. Ceramics is produced by sintering grains of silicon carbide to be bonded that have wide application in products needing high endurance, like car clutches, brakes and ceramic plates in bulletproof vests, electronic devices as light-emitting diodes or LEDs. SiC also has usage in electronics semiconductor devices operating at high voltages or temperatures.

Ceramic products made of Sintered Silicon Carbide Ceramic, Reaction Bonded Silicon Carbide and Silicon Nitride bond Silicon Carbide have wide range of application. Advanceceramic is one of the prominent suppliers and designers of these products in Shanghai.

Silicon Carbide Ceramic is fabricated usually with good quality Silicon Carbide at high temperature firing process using advanced formula. The formation of Silicon Carbide is usually done by Reaction bonding or sintering, and it affects the end products.

Reaction bonded Silicon carbide is manufactured by infiltration of compacts with mixtures of Carbon with liquid Silicon and SiC. The Silicon first reacts with Carbon creating a large number of SiC bonds with initial SiC particles. Whereas, sintered Silicon carbide is made from non-oxide sintering aids and pure SiC powder. Ceramic formation processes used are traditional and the material is sintered at 2000 degree temperature or higher in inert atmosphere. An environmental auditing must be drawn up to confirm that the manufacturing process is not hazardous for the human beings and environment.

The important chemical properties of the forms of Silicon Carbide (SiC) such as high wear resistance with good mechanical properties, high temperature strength and thermal shock resistance makes it a hugely used product. The engineers always advise that the weaknesses and strengths of each ceramic should be used for the particular need of customer.
