Lightweight silica bricks are mainly used for parts that need to be insulated or reduce weight without direct contact with molten materials, are not affected by aggressive gases, and are not subject to rapid temperature changes. Lightweight silica bricks are suitable for high-temperature environments such as glass kilns, hot blast furnaces, and charcoal kilns.

Lightweight silica bricks have excellent fire resistance, and their load softening temperature is close to that of dense silica bricks, reaching 1620 °C. Due to its porous structure, the thermal stability of lightweight silica bricks is better than that of dense silica bricks, which can be used for a long time under high temperature conditions without contacting us with slag. In addition, lightweight silica bricks have better thermal shock resistance, which is suitable for the lining of large blast furnaces supporting hot blast furnaces, glass kiln insulation layers, etc.

Specific application scenarios include:

Glass kilns: Lightweight silica bricks are more commonly used in glass kilns, mainly for insulation layers to reduce heat loss.

Hot blast furnace: suitable for large blast furnaces with hot blast furnace linings, improving thermal efficiency and durability.

Charcoal Stoves: Used in high-temperature environments like charcoal kilns to reduce dead weight while maintaining excellent thermal insulation properties.
