High-grade silica, mullite and fused-cast AZS refractories for glass furnaces, tin baths and regenerators.
Glass furnaces demand high-purity refractories with strong resistance to glass corrosion. The company supplies fused-cast AZS, silica, mullite and low-creep high-alumina bricks for tank walls, breastwalls, regenerators, ports and tin baths, with custom special shapes to drawing, timed to cold and medium overhauls.

Alumina bubble brick is made from fused alumina bubbles with high-purity alumina matrix, serving at 1600-1800°C with low thermal conductivity, good strength and direct flame contact for high-temperature kiln insulating and working layers.
Low-porosity fireclay brick with Al₂O₃≥45%, apparent porosity ≤15% and RUL ≥1400℃. High density resists penetration by glass melt and furnace gases.
Chrome-corundum brick (Al₂O₃≥90%, Cr₂O₃ 3-8%, refractoriness ≥1950℃) adds chromia to a corundum base for strong resistance to glass melt attack, slag and washout.
Mullite brick with mullite as the main phase (Al₂O₃≥75%, refractoriness ≥1850℃, RUL ≥1650℃) offers high-temperature volume stability with excellent thermal-shock and creep resistance.
Lightweight silica brick (SiO₂≥92%, 1550℃ max, bulk density 1.2-1.5 g/cm³, RUL ≥1550℃) combines silica refractoriness with lightweight insulation and matches silica brick thermal expansion.
Fused-cast AZS block (Al₂O₃≥48%, ZrO₂≥32%, bulk density ≥3.60 g/cm³, porosity ≤2%) is cast from the melt to near-zero porosity, giving outstanding resistance to glass-melt erosion and scouring.
Zirconia brick (ZrO₂≥95%, 2300℃ max, bulk density ≥5.20 g/cm³) with stabilized high-purity zirconia resists ultra-high-temperature melts and atmospheres—among the highest-temperature oxide refractories.
