For glass manufacturers worldwide, furnace downtime and inconsistent product quality are costly challenges. Traditional refractory bricks often fail prematurely under high-temperature glass liquid exposure—leading to unexpected shutdowns, increased maintenance costs, and even batch contamination. But what if a single material upgrade could extend furnace life by up to 40% while reducing defects?
Composite alumina-zirconia-silica (AZS) bricks—especially the AZS-33, AZS-36, and AZS-41 series—are engineered for extreme environments. Unlike conventional fireclay or silica bricks, these materials resist chemical attack from molten glass at temperatures exceeding 1500°C. Independent lab tests show they reduce leaching of alkali metals into glass by over 65%, ensuring consistent optical clarity and fewer rejects.
Not all furnaces are created equal. The right AZS grade depends on your process:
“After switching to AZS-41 bricks, our furnace uptime improved from 78% to 94%. We’ve saved over $120k annually in unplanned repairs.”
— Maria Lopez, Plant Manager, GlassTech Europe
