Product Introduction
Product Details
Product Overview:
Zircon mullite bricks have good chemical stability, with characteristics such as high temperature resistance, acid and alkali corrosion resistance, and thermal shock resistance. They are widely used in military, scientific research, high melting point metal smelting, laser crystals, quartz glass, electronics, and other industries in ultra-high temperature kilns and steel continuous casting.
Product Details:
Zircon mullite bricks are made from electric fused zirconia sand as raw material, sintered at high temperatures through a special process. They have good resistance to alkaline vapor and thermal shock, mainly used in the flame space of glass kilns, and can also be used in float glass kilns; alkali-free glass melting furnace pure oxygen combustion nozzle bricks, ceramic melting glaze kiln roofs, bricks, and other industrial kilns with high temperatures and significant thermal stress.
