There are many variations of alumina, and the common ones are α,γ Type A are all white crystals. Corundum in nature is α Type A belongs to the most dense hexagonal packing, with high melting point, high hardness, insoluble in acid and alkali, corrosion resistance, and good insulation. It can be obtained by co heating aluminum hydroxide with aluminum metahydroxide or aluminum ammonium alum at 723K γ Type A, insoluble in water, but with strong water absorption, strong adsorption capacity and catalytic activity. β It has ionic conductivity and allows Na+to pass through.

Aluminum Oxide Wholesaler

Aluminum oxide with high hardness can be used as abrasive, polishing powder, high-temperature sintered aluminum oxide, called artificial corundum or artificial gem, and can be used to make mechanical bearings or diamonds in clocks and watches. Alumina is also used as high-temperature refractory materials to make refractory bricks, crucibles, porcelain, artificial gemstones, etc. Alumina is also the raw material for aluminum smelting. It can be made by calcining aluminum hydroxide γ- Al2O3。 γ- Al2O3 has strong adsorption and catalytic activity and can be used as adsorbent and catalyst.

Aluminum oxide is suitable for a variety of dry and wet treatment processes. It can grind the rough surface of any workpiece finely. It is one of the most economical abrasives. This kind of sharp synthetic abrasive with rhombus has the hardness second only to that of diamond, and is especially suitable for use when there are strict requirements for iron pollution. It is used for the roughest cutting, and can also be made into pebbles to process workpieces with precise dimensions to achieve extremely low roughness. Because of its high density, sharp and rhombic structure, it is one of the fastest cutting abrasives.

Aluminum Oxide Producer

Alumina, the main component of corundum, is a barrel or cone shaped trigonal crystal. It has glass luster or diamond luster. The density is 3.9 ~ 4.1g/cm3, the hardness is 9, and the melting point is 2000 ± 15 ℃. It is insoluble in water, acid and alkali. High temperature resistance. The colorless and transparent one is called white jade, and the red one containing trace trivalent chromium is called ruby; Blue color containing divalent iron, trivalent iron or tetravalent titanium is called sapphire; The dark gray and dark color containing a small amount of ferric oxide is called corundum powder.

Frequently Asked Question

Do you have any question?

Firstly, We make sure the quality before the goods to be packed, if clients get the item with Substandard products, We have warranty for our clients,we will ship out the new replacements.

Al2O3 alumina is the starting material of aluminium production, both of metallic aluminium and aluminium oxide. It is porous an has a large reactive surface.

The refractive index of fused alumina is approx. 1.76, whereas that of normal glass types is approx. 1.4. The closer the refractive indices are to each other, the more transparent the system (e.g. varnishes).

Generally, we suggest to make shipment by sea which costs less. We also can follow other transportation method you asked.
