How to use the alumina crucible

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.
