The capacity of the crucible is 5 to 2000ml according to appearance, maximum capacity can be customized, and maximum size is 450mm. Under the general condition, the analyzed and fired substance is put into the crucible or a sagger and then put into analyzing or firing equipment to be heated. Heating and cooling speed is different according to the characteristics of the equipment and products. A raw material for manufacturing the crucible and the sagger is subjected to thermal expansion, and the crucible and the sagger are easily cracked if the heating or cooling speed is overhigh, so that the speed had better be low to prolong the service life of the crucible and the sagger. A corundum crucible contains 99.70% of corundum, has good high temperature insulation property and mechanical strength at the temperature of 1650 to 1700℃ in oxidizing atmosphere and reducing atmosphere, high heat conductivity and low thermal expansivity, does not react with air, water vapor, hydrogen, carbon monoxide and so on at the temperature of more than 1700℃, and has the short-term maximum service temperature of 1800℃.
