Introduction Silicon Carbide Melting Crucible
Silicon carbide melting crucible is the main parts of the chemical instruments. It is one container that can be used for melting, purification, heating and reaction. So many models and sizes are included, there is no limit from production, quantity or materials.
Silicon carbide melting crucible is a deep bowl shape ceramic containers which is widely used in metallurgy industry. When solids are heated by big fire, there must be a proper container. It is necessary to use a crucible while heating because it can withstand higher temperature than glassware and also ensure the 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.
Characteristics Silicon Carbide Melting Crucible
- Keep it dry and clean. Need to be heated to 500℃ slowly before using.
- Put materials into the silicon carbide melting crucible according to its cubage, keep proper space to avoid broken from thermal expansion.
- Try to use a spoon to take out the metallic solution, or choose a same shaped calliper which can protect the crucible damaged from local pressure difference.
- Avoid the strong oxidized fire burning directly onto the crucible. It will shorten the using time because of the material oxidation.
- 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 break and a wooden surface may cause a fire. Please leave it on a refractory brick or plate and let it cool down naturally.
