Alumina Ceramics:

Alumina is an important part of chemical instruments. It is a container for melting and refining metal liquids as well as solid-liquid heating and reaction. It is the basis for ensuring the smooth progress of chemical reactions.There are many model specifications, which are not limited by the production scale, batch size and smelting material type. They can be arbitrarily selected, have strong applicability, and can guarantee the purity of the smelted material.
1. Place the dry place after use and avoid rainwater intrusion; use it slowly to 500 degrees Celsius before use.
2, should be based on the volume of the feed, avoid too tight, so as not to cause thermal expansion and cracking of the metal.
3, when taking out the metal melt, it is best to use a spoon to pull out, try to use less calipers, if the use of calipers and other tools should be consistent with the shape of the ,, to avoid excessive local force and shorten the service life.
4. The service life of the crucible is related to the usage. The strong oxidizing flame should be prevented from being directly sprayed onto the crucible, and the raw material of the crucible is oxidized for a short life.
The raw materials for production can be summarized into three major types. One is crystalline natural graphite, the other is plastic refractory clay, and the third is calcined hard kaolin skeleton clinker. Since 2008, high-temperature resistant synthetic materials such as silicon carbide, alumina silicon carbide and ferrosilicon have been used as skeleton skeleton clinker. This clinker has a significant effect on improving the quality of niobium products, enhancing tantalum density and mechanical strength.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
