| Purpose | Main purpose of crucible and sagger is 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, analysis and melting of glass, analysis and firing of rare earth materials and mineral,firing of high temperature items such as ceramic products and melting of single-crystal raw materials. |
| Use | Under normal circumstances,firstly put the items which need to be analyzed and fired into the crucible or sagger.Then heat. 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 and saggers.The best way is slowing down,which can prolong the life of them. |
