1/1/1992· The characteristics and performance data for blue and violet light-emitting diodes (LEDs) made from silicon carbide (SiC) are presented. Existing technologies for the production of SiC pn structures (ion implantation, CVD epitaxy, and various modifiions of liquid-phase epitaxy) are considered, and the corresponding LEDs are compared on the basis of their rated performance.
8/3/2012· Silicon carbide (SiC) became an important material whose popularity has been constantly increasing in the last period due to its excellent mechanical, electrical, optical and chemical properties, which recommend it in difficult and demanding appliions.

23/6/1998· i) at least about 90 wt % silicon carbide grains, wherein at least 80 wt % of the silicon carbide grains have a diameter of between 0.5 and 5 um, ii) less than 5 wt % free silicon, and b) exposing the loaded boat to an environment having a temperature of between
Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).

INTRODUCTION Silicon carbide (SiC) is produced by mixing quartz sand and petrol coke in an electric resistance furnace (Smoak et al., 1978).Small-scale production of SiC was started by Edward Goodrich Acheson in the 1891 and has risen steadily since then (Smoak et al., 1978).).
