Aluminum Oxide Ceramic Crucible
My factory looking for distributors.
Crucible, as an important part of chemical equipment, is a reaction vessel for melting and refining liquid metal and heating solid-liquid. It is the basis for ensuring the smooth progress of chemical reactions. Historically, crucibles were originally made of clay, and one of the earliest uses of platinum was to make crucibles. But with the development of preparation technology, the crucible can now be made of any material that can melt or change its contents.

The crucible has many types, models and specifications, which can be selected at will, with strong applicability, and can ensure the purity of the material to be smelted. Among them, the ceramic crucible is an important part of the crucible. The ceramic crucible can be divided into alumina crucible, corundum crucible, quartz crucible, zirconia crucible and so on according to the raw materials. It is applied in different occasions according to their respective properties.
