alumina crucible 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 crucible 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.

MgO crucible 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 crucible 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.


Product Highlights:

-High purity

-Fully dense crucibles

-Excellent thermal shock resistance

-High temperature resistance



The main material of ceramic crucibles include Alumina, Zirconia, Magnesium oxide, Yttria,etc..
