Ceramic Crucibles Special oxide crucibles (Alumina/Zirconia/Magnesium oxide/Yttria)

HTC offers high purity and fully dense ceramic crucibes made from alumina, zirconia, magnesium oxide and yttria, etc.. The high purity ensure the cleanliness and superior reliability of the crucibles, it won't create pollutants or impurity in the process of melting.

 
Alumina crucibles(Al2O3)High purity alumina ceramics are ideal for high temperature applications. Alumina Crucibles are ideal for Broad applications, Tighter budgets, Repeatable performance and A service limit of 1700℃ in vacuum or oxidizing atmospheres.

 
Zirconia crucibles(ZrO2)Zirconia is more refractory, having a melting point some 500℃ above alumina. Zircoa crucibles are ideal for induction melting of superalloy metals, in vacuum or oxidizing atmospheres. Other markets served include: Aerospace, Crystal Growing, Dental, Mining and Precious Metals.

 
Magnesium oxide crucibles(MgO)Magnesium oxide crucibles is used for ultra-high temperature processing of metals, slags, and superconductor compounds. MgO ceramic is full-fired with high density, fine-grain microstructure. It offers alternative to alumina because it exhibits better chemical resistance and is inert.
 

Yttria crucibles (Y2O3) 

Fully dense yttria crucibles have lately attracted increasing interest because of the useful properties of this highly refractory material with a melting point of 2410℃. The yttrium oxide crucible material may be use for induction melting of titanium.
