Introduction to AZS Block

AZS block, also known as fused - cast alumina - zirconia - silica block, is a high - performance refractory material. It is produced by melting a mixture of alumina (Al₂O₃), zirconia (ZrO₂), and silica (SiO₂) at a very high temperature and then casting it into a specific shape. AZS blocks are widely used in the glass industry, especially in the construction of glass melting furnaces. Their excellent properties such as high refractoriness, good corrosion resistance against molten glass, and low glass infiltration make them indispensable for ensuring the long - term stable operation of glass furnaces and improving the quality of glass products.
