Calcined Bauxite 50/55/65/70/75/80/85/86/87% Alumina Content High Quality

 

1.Calcined Bauxite Description

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.

 

2.Main Features of Calcined Bauxite

Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum

hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .Calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .This removes moisture there. By increasing the alumina content,compared to an alumina content of about 57%to 58% in raw bauxite, calcined bauxite has an alumina content of 84%to88%.The heating is carried out in rotary kilns. 

 

3.Main usages of Calcined Bauxite

1.  aluminium industry.
2 . precision casting. 

3. for refractory products.
4.  aluminum silicate refractory fiber.

The above prices are from the Internet and for your reference only. Price may vary according to specific circumstances. I hope it can help you.
Q:How can refractory material of the electric furnace be used for longer.
Key: 1, consider the furnace size; As furnace volume differs, pressure of liquid iron (steel) on the crucible wall lining will not the same; 2, consider melting steel type: If different steels are melt, the erosion of steel liquid on the lining refractory is not the same; 3, give full consideration to the lining of the grain size distribution of the refractory material, otherwise, it will cause of refractory matrix size segregation. 4, regardless of the kind of refractory materials, take full consideration into the mineral phrase of refractory material, high temperature and other equal factors. 2011 - 01 - 05 Guangyi mineral
Q:How to make use of waste refractory materials whose main elements are alumina and mullite?
Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.
Q:What are the requirements of the performances of brasque refractory?
Physical properties of refractories include structural property, thermal property, mechanical property, usability and operation property. Structural properties of refractories include porosity, bulk density, water absorption, air permeability, pore size distribution,etc.. Refractory thermal properties include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, thermal emissivity. Mechanical properties of refractories include compression strength, tensile strength, breaking strength, torsional strength, shear strength, impact strength, abrasion resistance, creep property, bonding strength, elasticity modulus. usabilities of refractories include refractoriness, refractoriness under load, reheating linear change, thermal shock resistance, slag resistance, acid resistance, alkali resistance, water resistance, corrosion resistance to CO, conductivity, oxidation resistance, etc.. Operation properties of refractory include consistence, slump, fluidity, plasticity, cohesiveness, resilience, coagulability and hardenability,etc. I hope you can solve the problem with my answer.
Q:What are the electrical fire protection materials?
Flame retardant organic resin: They can be classied into PVC, vinyl chloride, chlorinated rubber, epoxy resin emulsion, epoxy resin, phenolic resin, etc.. Fire retardant additive: Phosphorus and halogens, nitrogen organic compounds (chlorinated paraffin, tributyl phosphate (TBP) and polybrominated diphenyl ethers) and boron (boric acid, zinc borate, boric acid aluminum), antimony, aluminum, zirconium inorganic compounds.
Q:What kind of foundry ingot refractory materials are there? Please be more detailed.
Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, etc.
Q:what's the application of fireproofing abs materials?
a kind of ABS alloy shell, a toy of child, low load bearing, refrigerator lining, it can be processed into various wear-resisting sheets, plates,and has good electrical performance, it can be used as electronic components or auto parts, all kinds of insulation materials, it's easy to machining on the surface, so it can be made into designated special products (such as electroplate), and easy coloring, it can be processed into colorful products, also can be used as a fireproofing electrical appliance outer covering, adding alloy to it will improve its comprehensive performance, etc
Q:What refractories are resistant to fluorine gas?
It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
Q:Which brand of refractory fiber hard thermal insulation board is better?
Thermal insulation materials are divided into two types: porous material and heat reflecting material. The former uses the air void contained in the material to maintain thermal insulation itself for the heat conductivity coefficient of air or inert gas within the voids is low, such as foam material, fibers and other materials; the latter material has a high coefficient of reflection which can reflect the heat, such as gold, silver, nickel, aluminum foil or metallic coated polyester and polyimide thin films. Aerospace industry has strict requirement for the weight and volume of thermal insulation material, and it is often also required to has the properties of noise absorption, vibration attenuation, and anti-corrosion. Different aircrafts have different requirements for thermal insulation materials. Aircraft cabin and cockpit usually use foam, ultra-fine glass wool, high silica cotton to maintain thermal insulation. Earlier missile head uses phenolic foam plastic as thermal insulating material. With the application of polyurethane foam with good thermal endurance, the single insulating material has been developed to sandwich construction. A few millimeters foaming coating is coated on the skin outside the missile instrument bay, it is anti-corrosion coating at room temperature and when aerodynamic heating reach 200 ° C or more, it will generate foam evenly thus maintaining thermal insulation. Artificial earth satellite moves in an environment where the temperature varies from high to low, so it must use laminated thermal insulation material with high reflecting performance, which is usually made up of dozens of layers of aluminum film, aluminized polyester film, and aluminized polyimide film. In addition, the successful development of the surface thermal insulated tiles has solved the problem of thermal insulation of the space shuttle, it also marks a higher level of development of insulation materials.
Q:Who knows how many fire heat preservation material are there?
Fire proof board is a fire refractory building material for surface decoration, widely used in interior decoration, furniture, kitchen cabinets, laboratories mesa, walls and other fields. Fire board is base paper (titanium powder paper, kraft paper) processed by melamine and phenolic resin, high temperature and high pressure. 1 mineral wool board, glass wool board: mineral wool, glass wool insulation. It does not burn itself, have good performance such as high temperature resistance, light quality. Such plate have evolved into plate with inorganic adhesive material as base material, mineral wool, glass wool as reinforcing material plate. 2 cement board: High strength, wide source. In the past, it is used to make fire prevention ceiling and partition wall, but its fire resistance is poor. Cement concrete component has good heat insulation and sound insulation performance. It can be used as the partition wall and the roof panel.
