Silicon carbide - Wikipedia
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).
Manufacturer of Silicon Carbide heating elements ( SIC …
It is ideal for the Silicon Carbide Elements to have their heating sections centered in the furnace chaer so that no portion of the heating section extends into the furnace wall. For heat to be radiated properly and the temperature to be maintained, a conical or truned cone-shaped recess inch deep is provided on each interior wall where the element passes through.
Preparation of a silicon carbide ceramic fiber by CO 2 …
It is known that at 1200-1400 degrees C the polycarlosilane (PC) can be converted into silicon carbide (SiC) by electric furnace heating. However, the production cycle is longer than ten hours owing to the limit to the raising rate of furnace temperature. A method of laser heat-treatment for preparation of SiC fiber is presented in this paper. As soon as PC precursor is made by a fiber

Vacuum Furnace Heating Elements
Heating element design and selection is critical to the proper functioning of any vacuum furnace and is dependent on a nuer of factors: maximum operating temperature; power load; partial pressure and quench gases and life expectancy. The vast majority of vacuum furnaces are electrically heated. As such, heating elements are constructed of either high-temperature metallic alloys such as
