Description

Calcined Bauxite 50-90% Alumina Refractory Raw Material

Bauxite (also known as alumina ore) is an earthy mineral primarily composed of alumina (aluminum oxide) along with various impurities, occurring in hydrated forms. It typically appears in white, off-white, brown, or light red hues due to iron content. With a density of 3.45 g/cm³ and a hardness of 1–3, it is brittle, opaque, and highly refractory. Bauxite is insoluble in water but soluble in sulfuric acid and sodium hydroxide solutions. It is mainly used in aluminum smelting and in the production of refractory materials.

Advantages

  • Low impurities ensure consistent refractory quality

  • Reliable supply for bulk and long-term use

  • High Al₂O₃ content suits mid- to high-grade refractories

  • Good sintering enhances strength in fired/unfired products

  • High refractoriness and thermal stability

Applications

  • Refractory products (refractoriness up to 1780°C)

  • Monolithic ladle linings (with magnesia sand)

  • Alumina cement, abrasives, ceramics, and chemicals

  • Aluminum smelting and derived industrial products

  • Refractory fiber production
