We can supply 95%, 99.7% alumina ceramic crucible and zirocnia ceramic crucible according to customer’s drawings, samples and performance requirement.

1.High purity>99.7% 

2.Max service temperature 1700.C

3.Good thermal shock

 

Zirconia (ZrO2) special crucible can withstand the high temperature up to 1700.C and has very good resistance to chemical erosions and thermal shock. Zirconia crucible is ideal for the melting of gold, glass, metal processing / molten glass, rapid thermal cycling, gemstone purification for jewelry industry etc.
