Product Desciption
When solids are heated by a big fire, there must be a proper container. It is necessary to use a crucible while heating because it can withstand higher temperatures than glassware and also ensure purity from pollution.
The silicon carbide melting crucible can not be overfilled by the molten contents cause the heated materials may be boiled and spraying out. Otherwise, it is also important to keep the air freely circulating for possible oxidation reactions.

Successful cases in large powder metallurgy industry
Notice:
1.Keep it dry and clean. Need to be heated to 500ºC slowly before use.
2.Put materials into the silicon carbide melting crucible according to its cubage, keep proper space to avoid broken from thermal expansion.
3.Try to use a spoon to take out the metallic solution or choose the same shaped caliper which can protect the crucible damaged from local pressure difference.
4.Avoid the strong oxidized fire burning directly onto the crucible. It will shorten the using time because of the material oxidation.
5.Do not place the heated silicon carbide melting crucible on a cold metal or a wooden surface immediately. A sudden cold will lead to cracks or breaks and a wooden surface may cause a fire. Please leave it on a refractory brick or plate and let it cool down naturally.
