Alumina Isostatic Pressing Crucible
Alumina Isostatic Pressing Crucible
Summary:
Isostatically pressed alumina crucibles are manufactured from high-purity alumina raw materials as the base matrix. The products feature extremely low chemical impurities to prevent contamination of molten materials during smelting. With uniform bulk density and internal non-delamination structure, they possess moderate air permeability, stable thermal conductivity and low thermal expansion coefficient, as well as outstanding thermal shock resistance to withstand frequent cold and hot cycles.
Product features:
1. Excellent resistance to slag erosion.
2. Improved thermal shock resistance.
3. Excellent abrasion resistance.
Range of application:
Suitable for melting a wide range of alloys and stainless steel, as well as induction furnaces, laboratory high-temperature sintering furnaces and other working conditions. It is a general-purpose refractory liner vessel for high-temperature melting.
