Bubble zirconia bricks are made by stabilized fused zirconia under high temperature. The products have many advantages, such as high temperature resistance, high strength, good thermal insulation, various acid-base erosion resistance and better thermal shock resistance.
Application: middle frequency furnace of tungsten and molybdenum, super high temperature kilns of refining of high-melting point metals, laser crystals, quartz glass industry.
