Production of silicon carbide rod in electric thermal industry
Silicon carbide (sic), also known as carborundum, is a compound of silicon and carbon with chemical formula sic. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics  that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests. Electronic applications of silicon carbide as light-emitting diodes (leds) and detectors in early radios were first demonstrated around 1907. Today sic is used in semiconductor electronics applications that are high-temperature, high-voltage or both. Large single crystals of silicon carbide can be grown by the lely method; they can be cut into gems known as synthetic moissanite. Silicon carbide with high surface area can be produced from sio2 contained in plant material.

Notice
What is the hardness should I choose?
Normally 20~40 Shore A will be the best, but it also should according to your size and pattern design.
Warm Tips:
The surfaces with which the material comes in contact must be perfectly clean, free of grease and dry.
Close the bottles after use so as not to confuse the cap of the catalyst with that of the base when re-sealing.
Be aware of possible cross-contamination; it's highly recommended to use only dedicated gear when processing poly-addition RTV2 silicone rubber (including degassing devices).
Be aware that contact with certain material can inhibit the curing of the RTV2 poly-addition silicone rubber. Common contaminants to be avoided include:
-Natural or synthetic rubber, vulcanized with sulphur derivatives.
-Poly-condensation RTV catalyzed with metallic salts.
-PVC stabilizing agents.
-Amine cured epoxies.
-Sulphur, tin and amines derivatives.
-In case of doubt, carry out a small test by pouring the mixture onto a small area of the object.
