Before small batteries were available, carbide lamps were used for bicycle lights. Acetylene gas, C2H2, and solid calcium hydroxide were formed by the reaction of calcium carbide, CaC2, with water.
Sintered silicon carbide is produced from pure silicon carbide powder with non-oxide sintering aids. It is a homogeneous form of sil-icon carbide that does not contain any free sil-icon. It also has an impervious structure requiring no impregnant. The absence of the free silicon makes Sintered chemically inert to virtually all corro-sive
