Materials
Aluminum oxide
High-purity aluminum oxide offers exceptional resistance to acidic and alkaline slags. It is a universal raw material for various alloys and melting applications in air or vacuum, with a maximum application temperature of 1620 °C.
Chromium-doped aluminum oxide
The chromium content improves resistance to slag attack and extends the product's lifespan. This material is ideally suited for melting in air, but not in a vacuum. The maximum application temperature is 1800 °C.
MgO-stabilized zirconium dioxide
Zirconium dioxide is extremely resistant to acidic shells. Doping with magnesium oxide prevents volumetric changes. The material is insensitive to Ni, Mo, Al, Fe, Pb, and Be and is widely used for melting alloys in a vacuum. Its exceptional thermal shock resistance and low erosion tendency ensure excellent melting results up to 2000 °C.
CaO-stabilized zirconium dioxide
Zirconium dioxide is extremely resistant to acidic slags. Doping with calcium oxide prevents volumetric changes. Due to its interaction with silicate slags, CaO-stabilized zirconium oxide is primarily used in the melting of platinum alloys. With very good thermal shock resistance and low erosion tendency, its maximum operating temperature is approximately 2000 °C.
Magnesium oxide
Magnesium oxide is extremely resistant to basic slags and is used in vacuum melting. The material is not wetted by nickel, cobalt, or iron. With a lower density than zirconium dioxide, magnesium oxide is preferred for X-ray analysis. The maximum operating temperature is 2000 °C.
