Crucible , density 6.00 , maximum using temperature 2200 ℃  , is mainly used in melting metals with stable thermal , its main purpose is to melt rare metalS . Zirconia crucible , with high temperature stability , is the idea experimental for high-temperature refractory products.

Anion ceramic perm plates which made of alumina material , are finished by dozens of procedures , with so many features like resistance , high strength good insulation , heat evenly and so on . It can resist over than 800℃ . The ceramic body is no cracking , smoothly surface , no damage to the hair when Sharply rise and fall temperature between-20 ℃ - 300℃ . Different colors can be customized according to customer requirements.
