2002/11/30· Silicon, likewise, will not let go of its four valence electrons, and does not even like to share them very much if the alternative of sharing them with an oxygen atom is possible. Both carbon and silicon find that hybrid sp 3 tetrahedral orbitals are the most stable, with the angle between bonds equal to 109° 28'', the tetrahedral angle .

General Information - Alloying Elements in Stainless Steel …
SiIicon (Si): Silicon is used as a deoxidising (killing) agent in the melting of steel and as a result most steels contain a small percentage of Silicon. Cobalt (Co): Cobalt becomes highly radioactive when exposed to the intense radiation of nuclear reactors, and, as a result, any stainless steel that is in nuclear service will have a Cobalt restriction, usually approximately 0.2% maximum.
98C - Black silicon carbide Contains 98% SiC and more amount of admixtures. Similarly to 99C, it is used for grinding of sintered carbides, ceramic materials, concrete, stone, rough grinding of castings (fettling) made of hard and fragile white cast iron and for cutting of concrete, stone and white cast iron.
