ELECTRICAL RESISTANCE HEATING ELEMENTS: AN OVERVIEW

SILICON CARBIDE Silicon carbide (SiC) exists only as a solid and, as it has no liquid phase, the material is rigid at all practical operating temperatures. This means that silicon carbide elements can be installed horizontally or vertically, without any additional supports, which simplifies the design of the equipment in which they are fitted.

Calcium Silicide - Methods of production and their

In this process calcium carbide is used in place of calcined lime. This calcium carbide along with silica and carbon produces calcium silicide according to the following reaction : At 1520°C 2 SiO2 + CaC2 + 2 C = CaSi, + 4 CO.
