High Zirconia Fused Cast Refractory
ZB-X950 Series
- Anti-Contamination
- High Corrosion Resistance
- High Electrical Resistivity
Developed using our advanced fused cast refractory manufacturing technology, the ZB-X950 Series is a super-premium fused cast refractory with exceptional properties.
It is highly resistant to the formation of stones and blisters in molten glass, making it ideal for contact areas in special glass melting furnaces requiring high quality.
It has been highly evaluated and proven in applications for specialty glass melting furnaces such as boro-silicate glass, glass ceramics, non-alkali glass, and alumino-silicate glass.
Features
01. Extremely High Corrosion Resistance
Using selected zirconia raw materials and optimal production conditions, we produce very dense fused cast refractories with zirconia content over 88%. They deliver outstanding corrosion resistance for direct contact with specialty molten glass, especially in areas where high corrosion resistance is required.
02. Excellent Anti-contamination
Strict quality control and high-purity zirconia raw materials ensure that defects such as impurities and blisters are unlikely to form in molten glass. This gives peace of mind for high-grade specialty glass manufacturing.
03. High Electrical Resistivity
Our proprietary formulation achieves high electrical resistivity, making these high zirconia fused cast refractories suitable for electrode blocks in all-electric glass melting furnaces.
