silicon brick

Silica bricks are manufactured from high-purity quartzite with added mineralizers, formed under high pressure and fired at elevated temperatures. Their distinctive properties include:

Superior high-temperature volume stability: Undergoes crystalline transformation at high temperatures to form stable tridymite and cristobalite structures

Excellent load-bearing softening temperature: Initial load-bearing softening temperature approaches its refractoriness, ensuring outstanding structural strength at high temperatures

Strong resistance to acidic slag erosion: Exhibits excellent resistance to acidic furnace slag and acidic gases

Low thermal conductivity at high temperatures: Helps reduce kiln heat loss and improve energy efficiency

Cost-effective operation: High cost-performance ratio, suitable for large-scale high-temperature equipment

Key Technical Parameters:

SiO₂ Content: ≥95%

Refractoriness: ≥1710°C

Load-bearing Softening Start Temperature (0.2MPa): ≥1650°C

Room Temperature Compressive Strength: ≥35 MPa

Apparent Porosity: ≤22%

True Density: ≤2.34 g/cm³

Silicon bricks are primarily used in the following high-temperature industrial sectors:

1. Coking industry: Critical areas such as coke oven roofs, walls, and combustion chambers

2. Glass industry: Lattice structures in glass melting furnace regenerators, upper walls, and roof structures

3. Iron and steel metallurgy: High-temperature sections of hot blast stoves and hot blast duct linings

4. Nonferrous metallurgy: Acidic sections of copper, lead, and zinc smelting furnaces

5. Ceramic industry: Kiln roofs and upper structures of ceramic kilns

6. Chemical industry: Lining for calciners and converters in sulfuric acid production
