Cheap High Purity Fused Aluminum Oxide Wholesale Canada

So far, two kinds of raw materials have been used in the production of corundum: one is directly fused or sintered with natural bauxite to white aluminum oxide, alumina corundum, sub-white corundum, etc .; the other is fused or sintered with industrial alumina. For white corundum, dense corundum, plate corundum, sintered corundum, etc. And more than 95% of industrial alumina is extracted using bauxite.

It can be seen that bauxite is an important raw material for the production of white fused alumina. Alumina and kaleite can also be used to extract alumina. The main minerals are gibbsite (Al2O3 · H2O) and gibbsite (Al2O3 · 3H2O). According to the different structure of corundum sand gibbsite, it can be divided into boehmite (or α-Al2O3 · H2O hard boehmite) and boehmite (or γ-Al2O3 · H2O boehmite, Baumeite).(cheap high purity fused aluminum oxide wholesale canada)

The so-called bauxite is not a mineral name, but a black alumina of boehmite, boehmite, and gibbsite. Its main chemical composition is Al2O3, with a general content of 40% to 80%. The magazines in the chemical composition of natural bauxite also vary greatly. In addition to Al2O3, there are also SiO2, TiO2, Fe2O3, CaO, MgO, K2O, Na2O, etc. Generally the same level, with similar aluminum oxide sandblasting media characteristics.

(cheap high purity fused aluminum oxide wholesale canada)These aluminum oxide for sand blaster chemical components constitute the following minerals: gibbsite, a Boehmite, and also sillimanite-based minerals (ie, sillimanite, andalusite, kyanite, whose chemical formula is (Al2O3 · SiO2), kaolinite (Al2O3 · SiO2 · H2O), rutile (TiO2) , As well as dicalcite and iron-containing minerals. Therefore, Al2O3 / SiO2 is low, most of black aluminum oxide abrasive 70 grit which are 4-7. Rhenium bauxite is also called high-alumina bauxite or bauxite. 

Rhenite bauxite mainly has oolitic, bean-like, detrital, and high purity fused aluminum oxide cryptocrystalline (mud-like) structures, as well as soil-like and dense block structures. All colors from white to ochre are generally red with high iron content and off-white with low iron content. Due to different cementing materials, the color changes greatly, and the advantages are reddish brown spots. The appearance black synthetic corundum characteristics of bauxite are more complicated, but there are also rules to follow.

(cheap high purity fused aluminum oxide wholesale canada)Bauxite in China is mainly distributed in Henan, Shanxi, Guangxi, Guizhou and Shandong provinces. The main black aluminum oxide blast media minerals are boehmite and kaolinite, followed by boehmite, gibbsite, rutile, dikasite, and iron-containing minerals. It is characterized by high Al2O3 content, high SiO2 content, and low Fe2O3 content. Except for Guangxi Pingguo bauxite, most of Fe2O3 is below 5%, and there are fewer high-quality pink aluminium oxide with Al2O3 / SiO2≥10.

For ore types, most of them are diaspore-kaolinite, aluminium oxide 36 grit commonly known as high-silicon-low-iron-hydrous bauxite-type bauxite, or high-alumina-high-silicon-low-iron-hydrous bauxite- Kaolinite-type bauxite. The bauxite in Pingguo, Guangxi can be called high-speed-iron bauxite-kaolinite type bauxite. The two minerals, gibbsite and kaolinite, constitute a series of aluminium oxide sandblasting with different Al2O3 content according to different proportions.(cheap high purity fused aluminum oxide wholesale canada)
