Product Description of Glass Kiln Fused Chrome Corundum Bricks
Introduce 10%~30% Cr₂O₃ into AZS-33. Since Cr₂O₃ can color molten glass, it is not suitable for colorless transparent glass, and its foaming index is also suboptimal. However, it is an ideal material for the upper structure of tank furnaces.
Colored glass melting furnaces can use Cr₂O₃-containing fused AZCS bricks for constructing tank walls to enhance corrosion resistance.
