Silicon Carbide(SiC) has become a promising material in semi-conductor industry, due to the development of SiC material manufacturing and the decrease of the cost in recent years.
Silicon Carbide (SiC) is a wide bandgap material and is the typical representative of the third-generation semiconductor materials. Due to the wide bandgap, high thermal conductivity, high saturated carrier mobility, high threshold breakdown electric field strength, and high chemical stability, it is an ideal substrate for the fabrication of power electronics and radio frequency devices operating at extreme environments, such as high temperature, high frequency, high power, and strong radiation. Therefore, SiC has extensive applications in white-light illumination, automobile electronic, radar communication, aeronautic and aerospace, and nuclear radiation.
We have the ability to make processing, like cutting, drilling, dicing, polishing, etc. We have rich experiences on the micro-machining on the hard but brittle materials.
silicon carbide ceramic beam as kiln furniture widely used for loading structure systems of high temperature industrial kilns. higher strength & no deformation even in 1700C Celcius working temperature, also longer life and excellent thermal conductivity make it save energy with less weight of the kiln car.

Because of the rarity of natural moissanite, most silicon carbide is synthetic. It is used as an abrasive, and more recently as a semiconductor and diamond simulant of gem quality. The simplest manufacturing process is to combine 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). Fine SiO2 particles in plant material (e.g. rice husks) can be converted to SiC by heating in the excess carbon from the organic material. The silica fume, which is a byproduct of producing silicon metal and ferrosilicon alloys, also can be converted to SiC by heating with graphite at 1,500 C (2,730 F).
