Carbon - Wikipedia

Carbon (from Latin: carbo "coal") is a chemical element with the syol C and atomic nuer 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth''s crust. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide

Silicon Carbide SiC Material Properties

Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.
