Organo-chlorosilanes are likewise incompatible with water or any hydroxyl compound – whether organic or inorganic in nature. These compounds are also similarly incompatible with oxygen. The products of such a hydroxyl compound (e.g., water, alcohol, glycol) and/or oxygen reaction include various silicon-carbon-oxygen bonded molecules, and a coination of hydrogen and hydrogen chloride.
Method of prepration of silicon carbide - definition The simplest manufacturing process is to coine silica sand and carbon in an furnace at a high temperature, between 1,600 0 C and 2,500 0 C . Fine S i O 2 particles in plant material (e.g. rice husks) can be converted to S i C by heating in the excess carbon from the organic material.

Naturally occurring silicon is composed of three stable isotopes, silicon-28, silicon-29, and silicon-30, with silicon-28 being the most abundant (92% natural abundance).  Out of these, only silicon-29 is of use in NMR and EPR spectroscopy.  Twenty radioisotopes have been characterized, with the most stable being silicon-32 with a half-life of 170 years, and silicon-31 with a half-life

Silicon carbide (SiC) has emerged as a promising semiconductor for photoalytic appliions due to its superior chemical stability, high charge mobility, and suitable energy band positions that straddle the water redox potential. 20,21 Most noticeably, SiC is
Reaction-sintered silicon carbide (RS-SiC), which is considered as a promising mirror material for space telescope systems, requires a high surface property. An ultrasmooth surface with a Ra surface roughness of 0.480 nm was obtained after water vapor plasma oxidation for 90 min followed by ceria slurry polishing for 40 min.
Silicon tetrachloride is a colorless, fuming liquid with a pungent odor. It is decomposed by water to hydrochloric acid with evolution of heat. It is corrosive to metals and tissue in the presence of moisture. It is used in smoke screens, to make various silicon containing chemicals, and in chemical analysis.

Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
Siliconized silicon carbide is a multiphase material, usually containing 7-15% silicon metal, a small amount of unreacted carbon, the remaining main body is SiC. Reaction bonded SiC materials are manufactured by various processes, depending on the required geometry, configuration and tolerances of the final product.

Description: Silicon Carbide is the only chemical compound of carbon and silicon.It was originally produced by a high temperature electro-chemical reaction of sand and carbon.Silicon carbide is an excellent abrasive and has been produced and made into grinding
Silicon reacts with halogens at high temperatures, forming volatile tetrahalides, such as SiF 4. Unlike carbon, silicon does not readily form double or triple bonds. Silicon compounds of the general formula SiX 4, where X is a highly electronegative group, can act as Lewis acids to form six-coordinate silicon.
Reaction Bonded silicon carbide is produced by infil-trating compacts made of silicon carbide and carbon with other type of silicon carbide, and being the most brittle material it tends to chip very easily. Both types have excellent abrasion resistance and work
