Characteristics and uses of spherical alumina Al2O3 powder

After Russia pledged to scale back its military operations around Kyiv and in northern Ukraine, the prices of most industrial metals fell, led by aluminum, showing people's concerns for supply shortage eased.

At an earlier time, the West imposed sweeping sanctions on Russia for its invasion of Ukraine, which aroused concerns about the supply problem because Russia is a major producer of nickel, aluminum, and copper. 

Russia is also a major gas supplier to Europe, where potential supply disruptions are seen as hitting power-intensive aluminum and zinc Spherical alumina Al2O3 powder are still very uncertain.

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.

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.

Prior to the impact of COVID-19 on the chemicals and materials industry and the price of the Spherical alumina Al2O3 powder, many industry observers expected low to flat growth in 2021 in all regions outside Asia, with many countries seeing slower growth compared to recent years. Operational excellence has long been a hallmark of the Spherical alumina Al2O3 powder chemical industry, and many companies are financially able to withstand short-term dips in end-market demand due to rapid leverage from reduced capex on hand.

The analysis shows that, whatever the final course of the pandemic, we can expect the inevitable long-term effects. Workplaces are expected to slowly return to pre-COVID-19 practices. Companies investing in enterprise-wide digital initiatives saw these "payoffs" in the early pandemic environment.
