Characteristics and uses of spherical alumina Al2O3 powder

 Overview of spherical alumina Al2O3 powder

Spherical alumina is an inorganic substance with the chemical formula Al2O3. It is a high hardness compound also known as bauxite in mining, ceramics and materials science. It is a white solid, insoluble in water, odorless and tasteless, and very hard in nature. It is easy to absorb moisture but not deliquescence (does not absorb moisture after burning). Alumina is a typical amphoteric oxide (corundum is α-shaped and belongs to the densest hexagonal compound. It is an inert compound, slightly soluble in acids and alkalis, and resistant to corrosion. It is soluble in inorganic acid and alkali solutions, but almost insoluble. Water and non-polar organic solvents; relative density (d204) 4.0; melting point 2050 ° C, boiling point 2980 ° C, ionized crystal at high temperature, commonly used in the manufacture of refractory materials.

Characteristics and uses of spherical alumina Al2O3 powder

Spherical alumina Al2O3 powder features: high filling density: large particle size, wide particle size distribution, high-density filling of rubber and plastics, low viscosity, good fluidity rubber compound; high thermal conductivity: compared with crystallization, high volume Density allows for higher thermal conductivity and heat dissipation of the composite; low abrasiveness: due to its spherical shape, there is less wear on kneaders, formers and dies.

Application of Spherical Alumina Al2O3 Powder

Spherical alumina Al2O3 powder is suitable for a variety of dry and wet treatment processes. It can finely grind the rough surface of any workpiece and is one of the most economical abrasives. The hardness of this sharp water chestnut synthetic abrasive is second only to that of diamond, and is especially suitable for occasions where iron contamination is strictly required. For the roughest cuts, it can also be made into pebble shapes to machine precision-sized workpieces with extremely low roughness. It is one of the fastest cutting abrasives due to its high density, sharpness and rhombohedral structure.

Spherical alumina Al2O3 powder is used to smelt high-quality bauxite to produce brown corundum, and high-quality aluminate is used to produce powdered corundum and white corundum. Their natural crystal structure makes them hard and tough. At the same time, they are also often used as raw materials for bonded abrasives and coated abrasives. Alumina Al2O3 can be recycled multiple times, the number of cycles depends on the grade of the material and the specific process. Most standard blasting equipment will work.

Spherical alumina Al2O3 powder is mainly used in the following aspects:

1. Paint: enamel paint, wear-resistant paint, plasma spraying.

2. Ceramics: transparent ceramics, bioceramics, alumina ceramics.

3. Petrochemical products: high-efficiency catalysts, catalyst carriers, and automobile exhaust purification materials.

4. Polishing materials: sub-micron/nano-level abrasive materials, single-crystal silicon wafer polishing, and precision polishing materials.

5. Lighting: long afterglow phosphor raw materials and rare earth tricolor phosphor raw materials, high pressure sodium tubes, LED lights, etc.

6. Electronic products: integrated circuit substrates, single crystal materials, far-infrared materials.

7. Cosmetics: cosmetic fillers.

8. Inorganic membrane materials.

Lithium nitride is the only stable alkali metal nitride

  Overview of Lithium Nitride  Li3N  Powder Lithium nitride is a metallic nitrogen compound with the molecular formula Li3N. It is the only stable alkali metal nitride. It is a purple or red crystalline solid, with a high melting point and a light green luster in reflected light and ruby color in transmitted light. Exposure to the air over a long period of time will eventually result in lithium carbonate. The chemistry of basic metal nitrides is extremely limited, and only lithium nitride is stable and easily prepared among binary compounds (sodium nitrite and potassium nitrite are prepared only under more extreme conditions). Lithium nitride belongs to the hexagonal crystal system. There are lithium and nitrogen layers composed of lithium and nitrogen atoms in lithium nitride crystal. The lithium atoms are arranged like carbon atoms in a graphite crystal, with nitrogen atoms at the center of a hexagon of lithium atoms. There is a lithium layer between the lithium and ni...

  Overview of Cuprous oxide  Cu2O  Powder Cuprous oxide,   the chemical formula is Cu2O, is monovalent copper oxide, a bright red powder solid, almost insoluble in water, in acidic solution disproportionation into copper and copper elemental, in the wet air gradually oxidized into black copper oxide. Cuprous oxide is mainly used in the manufacture of ship bottom antifouling paint(used to kill lower Marine animals), insecticides, and various copper salts, analytical reagents, red glass, but also used in the preparation of copper plating and copper plating alloy solution. Copper(I)oxide is also known as an inorganic compound of copper oxide with the chemical formula Cu2O. It's essentially covalent. The copper(I)oxide crystallizes in a cubic structure. When heated, hydrogen tends to reduce the disproportionation it undergoes in acidic solutions that produce copper (II) ions and copper. When the copper oxide is gently heated with metal copper, it is converted to cuprous ...

  Overview of Tungsten Disulfide Tungsten disulfide  as a potential battery material is also expected to benefit from more market replenishment. Tungsten disulfide is a layered material with remarkable surface effects, electron mobility, thermochemical stability and high electron density of states. It has been widely used for lithium and sodium storage. For example, nanocomposites as conductive additives or graphene composites as battery cathode materials can exhibit higher specific capacity and discharge efficiency, making up for the deficiencies of single-component WS2 or C as anode materials. The advent of sodium batteries is expected to alleviate the current shortage of lithium resources on the rapid development of the new energy industry, and will further stimulate the application of transition metal dichalcogenides such as tungsten disulfide WS2 in the field of power storage.  Lithium-ion batteries are a key raw material for developing energy devices and realizing t...
