Calcined bauxite best price

Bauxite, alumina or bauxite miner , main ingredients are aluminum oxide, hydrate alumina containing impurities,is an earthy mineral.White or grey, brown yellow or light red by iron.From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3, opaque, very brittle.Very difficult to melt.Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution.Mainly used for aluminium, refractory material.

Our produced 82% alumina calcined homogenized bauxite is made of selected bauxite as raw material, it is produced by multi-stage homogenization, wet grinding processes and high temperature calcination.  Our homogenized bauxite features homogeneous chemical composition and low content of impurities. It has stable microstructure by corundum and mullite crystal interspersed with each other. Besides, our bauxite has characteristics of good wear-resisting performance, small line ratio and excellent high temperature resistant corrosion. It is high quality raw material for high wear-resisting brick, blast furnace used corundum mullite brick, iron ditch castable applied to cement and power industry.

Chemicals:

Application:
1.  aluminium industry.Used for defense, aerospace, automotive, electrical, chemical industry, daily necessities, etc.

2 . precision casting. Alumina clinker made after mold precision casting processed into fine powder.Used in military industry, aerospace,

communications, instrumentation, machinery and medical equipment department.

3. for refractory products.High bauxite clinker as high as 1780 ℃ refractoriness, chemical stability strong, and good physical properties.

4.  aluminum silicate refractory fiber.With light weight, high temperature resistance, good thermal stability, low thermal conductivity,

heat capacity is small and the advantages of resistance to mechanical shock.Used in iron and steel, nonferrous metallurgy, electronics, petroleum,

chemical, aerospace, atomic energy, defense and other industries.

It is the high alumina clinker in the melting temperature of about 2000 ~ 2200 ℃ high temperature

electric arc furnace, via high pressure of high temperature melting, high-speed air or steam injection, cooling, became a white cotton - silicate aluminum refractory fiber.

It can be pressed into fiber blanket, board or woven cloth instead of smelting, chemical industry, glass and other industrial furnace lining brick.

Firefighters available refractory fiber cloth to make clothes.

5. with magnesia and bauxite clinker as raw material, add appropriate binder, used for pouring ladle whole ladle lining has particularly good effects.

6. manufacture alumina cement, abrasive materials, ceramic industry and chemical industry of aluminum compounds
