Castable Refractory Bauxite High Alumina Content Low Iron Refractory Raw Material

Leadsun Bauxite (also known as bauxite or aluminous earth) is a high-purity refractory raw material primarily composed of alumina (Al₂O₃), with impurities such as iron oxide, silica, and titanium oxide. It appears white, off-white, brown, or light red depending on iron content, and features high density (3.45 g/cm³), hardness, and refractoriness. Insoluble in water but soluble in sulfuric acid and sodium hydroxide solutions, it is a crucial raw material for aluminum smelting and high-performance refractory products.

• High Alumina Content: Available in grades from 50% to 90% Al₂O₃ to meet various refractory needs.
• Low Impurity Levels: Controlled Fe₂O₃, TiO₂, alkali, and alkaline earth content for consistent performance.
• High Bulk Density: Ranging from ≥2.45 to ≥3.30 g/cm³, ensuring dense and durable refractory structures.
• Excellent Refractoriness: Withstands extreme temperatures in furnace linings and metallurgical processes.
• Chemically Stable: Resistant to slag corrosion and thermal shock in harsh industrial environments.
• Versatile Applications: Suitable for refractory bricks, castables, cement, and aluminum production.
