Description

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. Alumina Tubes are available in different diameters and lengths.

Feature of alumina crucible:

high purity: Al2O3>99.5% well chemical corrosion resistance
Good temperature resistance, long time used at 1600ºC, short-term at 1800ºC.
Good thermal shock resistance, not easy to burst
Slip casting of high density

Shapes and capacity: We can make from 5ml to 6000ml. Our standard ones are, 10ml, 20ml, 30ml, 50ml, 100ml, 130ml, 150ml, 200ml, 1000ml, 2000ml etc

Product classification:
