Alumina crucible, tray and boat have various advantages of accuracy, low thermal conductivity, low coefficient of thermal expansion, non-deformation in high temperature, preeminent insulation and excellent corrosion resistance. They are widely applied to metal and metalloid melting in lab or industrial analysis, and competent in high temperature applications such as metal processing, glass melt,  rapid heating circle, gem purification and so on. ADCERAM® supplies numerous alumina crucibles, trays and boats to metallurgy, chemistry, nuclear, atomic enery, material industry, etc.

Alumina crucible is brittle due to its poor toughness, so operator should pay attention to handling gently and avoiding impact with careful check before use. Crack products must never be used.

The alumina crucible is supposed to be thoroughly dried before use.  If drying proceeds in an electric furnace, it must be ensured that the process is slow and without thermal shock.  Alumina crucible can`t be used in the furnace without heating and cooling rate adjustment, heating speed can`t exceed 50T/10minutes.  The highest heating temperature of alumina crucible is not allowed beyond 1700 ℃.
