Advantages of alumina crucible compared with other crucible:

1. Excellent high temperature performance: alumina crucible can be used at high temperatures, 

has a high melting point and chemical stability, can withstand temperature conditions. 

2. Good corrosion resistance: alumina crucible has good corrosion resistance to most acids, 

alkali, salt and other chemical substances, which can ensure the accuracy and safety of the experiment. 

3. High strength and good mechanical properties: alumina crucible has high mechanical strength and hardness, 

can withstand greater pressure and vibration, not easy to break or deformation. 

4. Good thermal conductivity: the alumina crucible has high thermal conductivity and can transfer heat quickly, 

which is conducive to the experiment. 

5. Long service life: alumina crucible has high hardness, is not easy to wear, can be used for a long time, 

reduce the cost of the experiment.
