AZS33-Y is an electrically fused zirconia alumina refractory material with approximately 33% zirconia content. Its unique microstructure and chemical composition enable exceptional performance in high-temperature environments:
High resistance to molten glass erosion: The addition of zirconia significantly enhances the material's resistance to molten glass erosion, extending furnace service life.
Superior thermal shock stability: Its low thermal expansion coefficient and uniform crystalline structure enable it to withstand abrupt temperature changes without cracking.
Low contamination: Extremely low leachate content ensures high purity of the glass melt, making it suitable for high-quality glass production.
Typical Physical Properties:
Bulk density: ≥3.75 g/cm³
Apparent porosity: ≤1.5%
Compressive strength at room temperature: ≥150 MPa
