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 Crucibles are available in many sizes and shapes.



Features for alumina ceramic crucibles 


1. High alumina purity:al2o3>99%,good corrosion resistance.

2. High temperature resistance,1600C in long use,1800C in short use.

3. Good thermal shock,no easy to crack.

4. High slip casting density

5. It is inert in hydrogen and carbonaceous atmospheres and offers high resistance to alkalies and other fluxes. It is suitable for glass melting, including borosilicate glass. Recommended for use with refractory metals such as molybdenum, platinum, rhodium, tungsten, tantalum and iridium.
