Precautions for the transportation and storage of alumina powder

The chemical formula of alumina powder is Al2O3, and the molecular weight is 101.96. The main component of alumina, white powder. There are different crystal forms, the common ones are α-Al2O3 and γ-Al2O3. Corundum in nature is α-Al2O3, hexagonal close-packed crystals. α-Al2O3 has a melting point of 2015±15°C, a density of 3.965g/cm3, and a hardness of 8.8. It is insoluble in water, acid or alkali. γ-Al2O3 is a cubic close-packed crystal, insoluble in water, but soluble in acid and alkali, and is a typical amphoteric oxide.


(1) Alumina powder should be stored in a cool, dry and well-ventilated warehouse.

(2) The storage place should be far away from fire and heat sources, and suitable materials should be prepared to contain the leakage.

(3) Keep the container sealed.

(4) It should be stored separately from the oxidant, and mixed storage should not be avoided.


(1) The packaging should be complete at the time of shipment, and the loading should be secure.

(2) During transportation, ensure that the container does not leak, collapse, fall, or be damaged.

(3) Mixed shipment and transportation with oxidants and edible chemicals are strictly prohibited.

(4) Avoid exposure to sunlight, rain and high temperature during transportation.

(5) After the vehicle is transported, it should be thoroughly cleaned.

We do the above points when transporting or storing alumina powder to ensure that the product maintains good performance and enables it to exert its original use effect in industrial production.

Two factors affecting the wear resistance of wear-resistant ceramic coatings

Wear-resistant ceramic coating (epoxy resin adhesive coating) has excellent wear resistance and is widely used in material protection and parts repair, such as parts scratches, casting defects, external cracks, part wear, and part leakage. Because the repair work is simple, efficient, and economically feasible, this process method has received increasing attention. What are the factors

What are the crystal forms of alumina powder

The crystal forms of Al2O3 are: α, γ, η, δ, θ, κ, χ and so on. When the external conditions change, the crystal form will change. In the Al2O3 variant, since the oxygen in α-Al2O3 (density 3.99g/cm3) is the most compactly packed, only α-Al2O3 (corundum) is stable, and other crystal forms are unstable. Transformed into
