Product Description

Alumina powder Made in China Supplier of Calcined Alumina Oxide price

It is widely used in various abrasive tools, wear-resistant fillers, and for preparing various ceramic grade and refractory grade micro powders. It is used as a raw material for high aluminum, high-purity structural ceramics, electronic components, high-frequency insulation ceramics, and high aluminum ceramic balls.

Technical Date Sheet:Molecular Formula: Al2O3H.S. CODE: 2818 2000CAS No.:1344-28-1Nickname: high-temperature aluminaColor/Appearance: White powderCalcined Alumina is a high-purity, anhydrous form of alumina produced by heating bauxite at high temperatures (above 1000°C). It is primarily used in applications requiring excellent hardness, high melting point, and chemical stability. Calcined alumina is widely utilized in the ceramic, refractory, and abrasive industries, as well as in the production of spark plugs, electronic components, and catalysts.

Key Properties

25kg/bag or 50kg/bag, 24Tons/20GP with pallets. 27Tons/20GP without pallets. Offer customized packaging printing services.

Product Description High Purity: Industrial-grade calcined alumina typically has an AL2O3 purity of 99.0%-99.9%, while high-purity grades can exceed 99.99%. Low levels of impurities such as SiO2, Fe2O3, and Na2O ensure excellent performance in demanding applications. Thermal Stability: It has a high melting point of approximately 2,072°C and maintains structural integrity at elevated temperatures, making it ideal for high-temperature environments. Mechanical Strength: Wear resistance, suitable for abrasive and structural applications. Product Application

1. • Gamma-alumina serves as a catalyst support in petrochemical processes (e.g., oil refining and hydrogenation reactions) and as an adsorbent for water treatment and gas purification.
   • Other Fields: It is also used in the production of aluminum metal (as a raw material for electrolysis), glass (to improve hardness and heat resistance), and cosmetics (as a thickener and abrasive in skincare products).
   Ceramics Industry: It is the core raw material for advanced ceramics, used to produce alumina ceramics, porcelain insulators, ceramic substrates for electronic components, and wear-resistant ceramic parts. These products are widely applied in electronics, automotive, and aerospace fields.
   Refractory Materials: Calcined alumina is a key component of high-temperature refractories, used to manufacture refractory bricks, castables, and refractory coatings for steelmaking furnaces, cement kilns, and glass melting furnaces, improving their heat resistance and service life.
   Abrasives: Due to its high hardness, it is used to produce abrasive tools such as grinding wheels, sandpapers, and cutting discs, as well as abrasive grains for precision grinding and polishing of metals, glass, and semiconductors.
   Electronics and Catalysis: High-purity alpha-alumina is used for LED sapphire substrates and semiconductor wafer carriers.
