Operating Guide 

At ambient temperature, firstly put the items which need to be analyzed and fired into the crucible or sagger. The speed of heating and drop in temperature are  according to the characteristics of equipment and products, fast or slow.Because of the thermal expansion of raw material which the crucibles and saggers are made of, too quick heating or cooling will easily lead to cracking of  the crucibles or saggers.The best way is slowing down, which can prolong the life of them.

 

Applications

Alumina ceramic crucible or sagger is mainly used as a container for analysis and firing of material and product applied in various industries. For example: analysis of coal, melting of the metal, analysis and firing of chemical raw materials, glass, rare earth materials and mineral,firing of high temperature items such as ceramic products and melting of single-crystal raw materials.
