Frequently Asked Questions

What are the key advantages of electrofusion recombined zirconium corundum bricks?

Our electrofusion AZS bricks offer superior high-temperature resistance up to 1790°C, excellent corrosion resistance to molten glass, low apparent porosity (17-18%), and exceptional structural integrity under thermal cycling conditions. The electrofusion manufacturing process creates a dense, homogeneous structure with minimal glass phase content, resulting in outstanding performance in the most demanding glass furnace applications.

Which grade should I choose for my glass furnace application?

AZS-30 is ideal for high-stress areas requiring maximum corrosion resistance with its 30% minimum zirconia content, making it perfect for pool walls and throat applications. AZS-26 offers balanced performance for general glass furnace applications with optimised cost-effectiveness. AZS-20 cross tiles are specifically designed for areas requiring higher alumina content (70% minimum) and are excellent for specialised furnace configurations and installations requiring precise dimensional tolerances.

What quality certifications do these products meet?

Our AZS bricks are manufactured according to ISO 9001:2015 quality management standards and comply with ASTM International specifications (including ASTM C24, C20, C133, and C16), JIS Japanese Industrial Standards, EN European Standards, and GB/T Chinese National Standards. All products undergo rigorous quality testing including XRF chemical analysis, thermal cycling tests, and dimensional verification to ensure consistent performance and reliability.
