Product Description:

High Pure Whiteness Aluminium Powder Al2o3


Specification:

It is a kind of aluminate cement wrought material based upon calcium aluminate, it is called Aluminate cement when it has been finegrinded to hydraulicity cementing material, its code is CA. When the cement has a grinded Al2O3 content of above 68%, it can be added with appropriate amount of α-Al2O3 powder as requirement.

 

Application:

1. aluminium oxide for aluminium smelting, glass, ceramic industry etc.

2. aluminium oxide for refractory, coating, abrasive applications.

3. aluminium oxide for electric basal plate, desiccating agent, chemical and pharmacy industry, etc.

 

aluminum oxide property:

It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. As the abrasive materials, it is suitable for grinding high-speed, high carbon steel, as loose grains, it widely used for bonded and coated abrasives , polishing, precision casting and so on .

white fused alumina grits&powder chemical composition

 

aluminum oxide property:

Soluble in water white solid. Odourless. Tasteless. Qualitative very hard. Easy absorption of moisture and not ChaoXie. Both sexes oxide, soluble in inorganic acid and alkaline solution, almost insoluble in water and the polar organic solvents. The relative density (d204) 4.0. Melting point about 2000 °C.

 

The physical and chemical analysis:

 

 High Pure Whiteness Aluminium Powder Al2o3

 

Main standard:

Alumina(industry grade) made by slkali-lime sintered,It is white powdered crystal with low assay of Ti, Mn, Zn, Cu, V, Zr, Cr, Li, Pb, B, P, etc.It is used in the production of fused salt eletrorefining aluminium, corundum eramics, refractories and other alumina chemical products.

Q:Which company needs the new refractories?
The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.
Q:which kind of material should be used in fireproofing cabinet?
Cabinet fireproof panel can be divided into fiber cement fireproofing board, metal fireproof panel, mineral wool fireproof panel, perlite fireproof panel and many other fireproof panels. Wherein fiber cement fireproofing board is a new material with growing popularity , it has good thermal insulation and sound insulation performance and belongs to a1 level fireproofing material. Fiber cement fireproofing board is a kind of decoration sheet that takes silicious material or calcareous material as the main raw materials and is made by being combined with fibrous material and other additives in certain proportion. Metal fireproof panel is a kind of sandwich dalle that takes aluminium plate, stainless steel plate, colorful steel plate and other metal materials as main raw materials and is made by adding some fire retardant materials. Mineral wool board is a kind of fireproofing decorative board that takes mineral wool and glass wool as the main raw materials. Perlite fireproof panel is a kind of fireproofing hollow plate that take low alkalinity cement as the main materials and fireproofing perlite as filler.
Q:What materials is silicious thermal insulation board made of?
Refractories that contain more than 93% of the monox are acidic refractory materials which include ordinary silica brick, high-density and high-purity silica brick, silica brick that contains chromium, fused quartz products, unburned brick and siliceous ramming materials. It has good softening temperature under a fixed load and can resist corrosion of acid slag, but will have chemical reaction with alkaline slag. Silicious refractory of industrial value mainly is crystalline quartz, such as α and β quartz, tridymite and cristobalite.
Q:What are Grade-A waterproof inorganic thermal insulation materials?
1. Foam ceramic insulation board Foam ceramic insulation board is made of inorganic ceramic material by high temperature baking and is called ceramic insulation plate for short. 2. Composite cement foaming insulation board With cement, fly-ash and micro-silica, composite cement foaming insulation board is a kind of hole-closed lightweight hydrophobic insulation board made by foaming, maintenance,cuttign and processing. 3. Aerated concrete panel Using lightweight material, silicious material and foaming agent and so on, aerated concrete panel is a lightweight concrete panel made by high pressure steaming. 4. Rock wool board With natural igneous rock as material and thermosetting resin as binder, rock wool board is a panel made by melting in high temperature through centrifugation. I hope it can help you.
Q:Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?
Different fire resistant ratings of buildings require different fire endurance of different elements of buildings. According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level.
Q:How is refractory material made?
It is made by mixing and processing of various refractories.
Q:What are the new refractories?
Most are ordinary refractories.
Q:Which schools are the best schools in the world for learning knowledge about refractories?
Wish it helps you out.
Q:What are the refractory materials above 1000℃
corundum would be fine
Q:What is unshaped refractory?
Plastic. From the production method, the plastic is between the concrete and the castable. It is made of refractory material by refractory material plant, which is made of plastic clay. The ingredient is a retarder. It is packaged by plastic bag, and construction and heat treatment are carried out on the spot. But the biggest problem is the application of plastic on the knotted Jiecha easy peeling, retarder dosage improper or is vulnerable to bad caking plastic hardening.
