Spherical alumina Al2O3 powder overview:
Alumina is an inorganic substance with the chemical formula Al2O3.It is a high-hardness compound and is also called bauxite in mining,ceramics and materials science.It is a white solid insoluble in water,odorless,tasteless,and very hard in nature.It is easy to absorb moisture but does not deliquescence (non-hygroscopic after burning).Alumina is a typical amphoteric oxide (corundum is alpha-shaped and belongs to the most densely packed hexagonal compound.It is an inert compound,slightly soluble in acid and alkali and corrosion resistant. It is soluble in inorganic acids and alkaline solutions,but almost insoluble in water And non-polar organic solvents;relative density (d204) 4.0;melting point 2050°C,boiling point 2980°C,ionized ionic crystals at high temperature,often used to make refractory materials.
Industrial alumina is prepared from bauxite (Al2O3·3H2O) and diaspore.For Al2O3 with high purity requirements,it is generally prepared by chemical methods.There are many different crystals of Al2O3.There are more than 10 kinds of known crystals.There are mainly 3 crystal types,namely α-Al2O3,β-Al2O3,and γ-Al2O3.Among them,the structure is different and the properties are different,and it is almost completely transformed into α-Al2O3 at a high temperature above 1300℃.
Spherical alumina Al2O3 powder features:high packing density:with larger particle size and wide particle size distribution,it can realize high-density packing of rubber and plastic,and produce compounds with low viscosity and good fluidity;high thermal conductivity:Compared with crystalline silica,the high packing density can make the thermal conductivity and heat dissipation rate of the compound higher;
Low abrasiveness:Due to its spherical shape,the kneader,molding machine and mold wear less.
Alumina is used to produce brown corundum by fusing high-quality bauxite ore,while high-quality aluminate is used to produce powder corundum and white corundum.Their natural crystal structure makes them hard and fast.At the same time,they are often used as raw materials for bonded abrasive tools and coated abrasive tools.Alumina can be recycled many times,and the number of cycles is related to the grade of material and the specific process.Most standard abrasive blasting equipment can be used.
Spherical alumina Al2O3 powder should be stored in a dry,cool and sealed environment,and should not be exposed to the air.In addition,avoid heavy pressure and transport it as ordinary goods.Packed in a double-layer plastic bag inside,it can be filled with argon in a vacuum;it can be vacuumed and filled with argon for protection.Vacuum packaging,100G,500G or 1KG/bag,25kg/drum,or as your requirement.
Spherical alumina Al2O3 powder application:
1.Paint:porcelain paint,wear-resistant paint and plasma spraying.
2.Ceramics:transparent ceramics,bio-ceramics and alumina ceramics.
3.Petrochemical products:high-efficiency catalysts,catalyst carriers and automotive exhaust gas purification materials.
4.Polishing materials:sub-micron/nano-level abrasive materials,single crystal silicon wafer polishing,precision polishing materials.
5.Illumination:Long afterglow phosphor raw materials and rare earth three-color phosphor raw materialshigh-pressure sodium lamp tubes, LED lights,etc.
6.Electronic products:integrated circuit substrates,single crystal materials and far infrared materials.
7.Cosmetics: cosmetic fillers.
8.Inorganic membrane materials.
Alumina is suitable for a variety of wet and dry treatment processes.It can grind the rough surface of any workpiece finely.It is one of the most economical abrasives.This kind of sharp and water chestnut synthetic abrasive has hardness second only to diamond,and is especially suitable for use when there are strict requirements for iron pollution.Used for the roughest cutting,it can also be made into a pebble shape to process precision-sized workpieces to achieve extremely low roughness.Due to its high density,sharpness,and rhombohedral structure,it is one of the fastest cutting abrasives.
