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.
