   • Features: Low true density (< 2.35) and impressive softening temperatures (1640-1680°C), though they exhibit limited thermal shock resistance.

2. Aluminosilicate Refractories

   • Includes: Fused silica products, semi-silica bricks, phyllite bricks, clay bricks, high alumina bricks, and mullite bricks.
   • Benefits: Exceptional thermal shock resistance and low thermal conductivity, making them perfect for high-demand environments in the metallurgical sector.

3. Fused Silica Products

   • Material: Pure fused silica.
   • Advantages: Features a low linear expansion coefficient and robust thermal shock resistance, although care is needed for prolonged use above 1100°C.

4. Semi-Silica Bricks / Phyllite Bricks

   • Composition: 15-30% Al2O3, > 65% SiO2.
   • Applications: Perfect for coke ovens and acidic iron furnaces.
   • Characteristics: Minimal volume change with beneficial micro-expansion for enhanced airtightness.

5. Clay Bricks

   • Composition: 30-48% Al2O3.
   • Features: Excellent refractoriness (1580-1750°C) and thermal shock resistance, suitable for various furnace applications.

6. High Alumina Bricks

   • Composition: Over 48% Al2O3.
   • Features: High softening temperatures (1420-1550°C), ensuring reliability in extreme conditions.

7. Mullite Bricks

   • Composition: Synthetically produced mullite.
   • Advantages: Superior high-temperature performance and creep resistance, outpacing traditional high alumina bricks.

8. Silica Stone and Red Column Stone Bricks

   • Characteristics: Low thermal expansion and high wear resistance, perfect for resisting harsh environments in metallurgy and glass production.

9. Silica-Mullite Bricks

   • Features: High compressive strength and thermal shock stability, essential for demanding applications.
