Characteristics and uses of spherical alumina Al2O3 powder
Analysts at JPMorgan recommended selling or "underweight" emerging market local currency sovereign debt because of the global impact of the Ukraine-Russia crisis.
JPMorgan estimated that fixed-income assets in emerging markets have lost 6-9 percent of their value since Russia invaded Ukraine a month ago, with nervousness about the war and its impact on global energy and food prices adding to existing pressures.
Some leading emerging market central banks are signaling that interest rates now need to rise faster than previously expected, which fuels fears of "stagflation". Stagflation means when high inflation and higher interest rates undermine economic growth.
With both the U.S. Federal Reserve and emerging market central banks raising interest rates, JPMorgan also said it made sense to "underweight" emerging market assets by taking advantage of the recent pullback in local currency bond yields relative to TREASURIES.
JPMorgan said major metals exporters such as South Africa, Chile, and Peru could still do well, but warned that emerging market fixed income assets now faced a more "stagflationary" trajectory.
The markets and prices of many commodities, metals, chemicals like the Spherical alumina Al2O3 powder still face uncertainty.
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.
