Glass Furnace Repair Applications
High-Purity Fused Silica for Hot Repair & Furnace Maintenance
Fused silica is widely used in glass furnace repair and maintenance due to its exceptional thermal shock resistance, chemical purity, and stability at extreme temperatures.
Fused Silica for Glass Furnace Repair
Glass furnaces operate continuously at extremely high temperatures, making repair materials subject to severe thermal stress and chemical attack.
Fused silica is an ideal material for hot repair and cold repair applications, especially in areas exposed to molten glass and rapid temperature changes.
Its low thermal expansion and high SiO₂ purity ensure reliable performance during furnace maintenance operations.
Typical Glass Furnace Repair Applications
Fused silica is commonly used in:
Hot repair materials for glass furnaces
Furnace patching and sealing compounds
Glass contact areas
Burner blocks and working end repairs
Emergency repair and maintenance materials
It is suitable for float glass, container glass, and specialty glass furnaces.
