Abstract:
Silicon Carbide crucibles are made
out of silicon carbide and graphite
utilizing tar pitch or other synthetic resins
as bonding materials. These are highly
refractory products used for melting
ferrous and non-ferrous metals and
alloys in the foundries due to their
superb inherent properties such as good
thermal conductivity, low thermal
expansion, resistance to thermal
shocks, resistance to wetting to molten
metals, etc. when compared to clay
bonded graphite crucibles. These
crucibles are mostly used for melting
non-ferrous precious metals such as
brass, copper, nickel, chromium as well
as their alloys.
