Question

what do you mean by graphite crucibles??

give right answer ..there is no need to write anything which is not related to this...​

Answer 1

Graphite Foundry Crucibles. Ideal for open-flame applications; primarily used in propane furnaces. *These are consumable items, especially when working with metals at very high temperatures. Effectively melts gold, silver, copper, brass, aluminum, and more.

deal for small scale melting processes. Our high-density graphite crucible cups work great when melting metals. ... Browse our large selection of induction furnace crucibles. Performance characteristics include good electrical resistance, good thermal conductivity, and high resistance to chemical corrosion.

Explanation:

A crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot.

Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and other metals.

Quartz crucible has the advantages of high purity ,high temperature resistance, with big size ,good thermal insulation, economization on energy ,quality stability etc.

Fused quartz crucibles are used in the manufacture of silicon metal for semiconductor wafer applications and polysilicon. In order to produce high quality wafers, starting materials are added to a crucible heated to high temperatures and pulled from the melt as a single crystal. Fused Quartz is one of the few materials that can combine the high purity and high temperature properties required for this process.
