Silicon carbide Guide, Meaning , Facts, Information and Description
Silicon carbide (SiC) or moissanite is a ceramic compound of silicon and carbon.
Most SiC is man-made for use as an abrasive (when it is often known by the trade name carborundum), or more recently as a semiconductor and moissanite gemstones. The simplest manufacturing process is to combine sand and carbon at a high temperature, between 1600°C and 2500°C. Purer product can be made by the more expensive process of chemical vapor deposition. Its high melting point (above 1600°C) makes it useful for bearings and furnace parts. It is also highly inert. There is currently much interest in its use in electronics, where its high thermal conductivity, high electric field breakdown strength and high maximum current density make it more promising than silicon for high-powered devices.
Use as semiconductor
SiC is used for blue LEDs, ultrafast Schottky diodes and MESFETs. Due to its high thermal conductivity, SiC is also used as substrate for other semiconductor materials.
