AZS is an acronym that stands for "Alumina-Zirconia-Silica". It refers to a high-quality refractory material composed of three main components: alumina (Al2O3), zirconia (ZrO2), and silica (SiO2).
AZS is primarily used in the production of glass, especially in areas where glass-making furnaces and kilns are subjected to extreme temperature conditions and aggressive chemical reactions. The combination of these three compounds in AZS creates a material that exhibits excellent resistance to thermal shock, corrosion, and erosion, making it highly suitable for such applications.
The high alumina content in AZS provides it with strong thermal stability and resistance to alkaline attack, which is crucial to withstand the high temperatures involved in glass production. The addition of zirconia further enhances its strength and resistance to thermal shock by inhibiting the growth of harmful crystals that can cause structural failure. Additionally, the silica content helps in maintaining the overall integrity and low thermal expansion of AZS.
AZS is commonly used in glass refractory brick linings, crowns, superstructure blocks, and other components of glass furnace structures. It is highly valued for its durability, long service life, and ability to withstand repeated heating and cooling cycles.
In summary, AZS is a refractory material consisting of alumina, zirconia, and silica. It offers exceptional resistance to thermal shock, corrosion, and erosion, making it a preferred choice for glass furnace linings and other applications requiring high-temperature resistance and durability.
