Crucible is an important part of chemical instrument. It is a vessel for melting and refining metal liquids, heating and reaction of solid and liquid. It is the basis for ensuring the smooth progress of chemical reaction.
The crucible has many types and specifications. It is not limited by the production scale, batch size and the variety of melted materials. It can be chosen arbitrarily and has strong applicability, and can ensure the purity of the melted materials.
Use precautions:
1. Place it in a dry place after use. Do not let rainwater invade it. Bake it slowly until 500 degrees Celsius before use.
2. The crucible should be fed according to the capacity of the crucible, so that the crucible should not be squeezed too tightly to avoid thermal expansion and cracking of the metal.
3. When removing the molten metal, it is better to scoop it out with a spoon and use as few calipers as possible. If using calipers and other tools should match the shape of the crucible, avoid excessive local force and shorten the service life.
4. The service life of crucible is related to its usage. It is necessary to avoid strong oxidation flame spraying directly on crucible and make crucible raw material short-lived.
