Silicon - Wikipedia

Silicon is a chemical element with the syol Si and atomic nuer 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor.It is a meer of group 14 in the periodic table: carbon is above it; and germanium, tin, lead and flerovium,are below it.

silicon carbide fibres and their potential for use in …

Silicon carbide (SiC) has been considered as potential high-temperature material with high strength and chemical stability. The bonding of SiC to metals is useful to develop the appliions. However, when SiC is bonded directly to metals, the serious reaction weakens the bond.

Fluidized bed roasting of zinc sulfide concentrate : factors …

An experimental programme was established to study the effect of process parameters on the agglomeration behaviour of particles within a fluidized bed zinc concentrate roaster. A 102 mm internal diameter pilot scale roaster was designed, constructed and commissioned. Tests were then conducted with two industrial zinc concentrates at different temperatures (875-975C), superficial gas velocities
