Alumina (Al2O3) has a wide application due to its versatility and low material cost. Alumina possesses a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion.
The recommended maximum service temperature for alumina products is 1750 Celsius Degree.  Alumina products are sensitive to thermal shock.  So it is important to keep slow temperature change rate and even heating during the process.  Some general usage guidelines are as below:
Alumina products are fragile. Please handle them carefully and avoid collision during unpacking, transportation, handling and cleaning.
Check whether any micro-cracks exist before using alumina products. Products with micro-cracks should not be used.
Alumina products should be completely dry before usage. If they get wet, let the crucible or tube dry naturally before using them. If dry alumina products by placing in a dryer or oven, make sure that the dry process goes slowly.
Alumina products are sensitive to thermal shock. Try to slowly heat up/cool down and avoid uneven heating whenever possible.  A 3°C/minute temperature change rate is recommended.
Avoid contact of heated alumina products with a cold surface.
