γ-alumina powder is a transitional alumina material with high specific surface area, rich mesoporous structure and surface acidic sites, and has excellent thermal stability and chemical inertness. It has good fluidity, is soluble in acid and alkali solutions, has strong water absorption in the air, and has moderate particle size. Its porous properties and adjustable pore size distribution make it an ideal catalyst carrier and adsorbent. At the same time, its easy surface modification facilitates metal loading or functional modification. In addition, γ-Al₂O₃ powder also has the characteristics of low density and good dispersibility, and is widely used in petrochemical, environmental protection, new energy, biomedicine and other fields.
It is used as raw material for the pesticide production of new fungicide fosetyl aluminum, Vb12 adsorbent in pharmaceutical production, and active filler in the paint production, and also a good raw material for catalysts and anhydrous aluminum chloride, widely applied in the pharmaceutical, chemical and other industries.
