    Product Detail

    Brief Introduction

    Fused cast zirconia blocks are high zirconia refractories made by melting high purity raw materials through special casting process. The series of molten high zirconium bricks mainly includes RTK-Z9540 (zirconium content >89%) and RTK-Z9510 (zirconium content >93%). RTK-Z9540 Mineral composition: ZrO₂ (89 %), SiO₂ (9%), Na₂O (0.05%).

    The crystalline structure of fused cast zirconia blocks is mainly composed of baddeleyite, so it has extremely high corrosion resistance and low foaming rate characteristics. These advantages effectively prevent the contamination of the molten glass.

    Fused cast zirconia block can be widely used in various glass furnaces, especially high quality and special glass furnaces, such as liquid crystal substrate glass furnace, high alumina glass furnace, borosilicate glass furnace, halogen lighting glass furnace, glass ceramic furnace, glass fiber furnace etc.

    Zirconia refractory products are produced with PLC programmed special electric furnace and special material incubator. During casting, the shrinkage cavity block is obtained after molding. This casting method is generally used for cast zirconia block products.

    Fused cast high zirconium brick is one of our four core products. The main physical and chemical indexes of the high zirconium brick series products produced by Reftech have reached the level of international mainstream suppliers, and the quality of products can be fully guaranteed.
