Russia and Ukraine is an important exporters of oil, natural gas, metals, fertilizers, rare gases and other industrial raw materials. Affected by the further intensification of the tension of the war, the global market has become more worried about the supply of the spherical aluminum oxide, and panic spreads in the futures market. Prices of commodities such as aluminum and nickel are at recent highs on concerns that supplies will fall. Russia accounts for 49 percent of global exports of nickel, 42 percent of palladium, 26 percent of aluminum and 13 percent of platinum, and is a significant exporter of steel and copper. Palladium is an important metal for sensors and memory. In addition, Russia is the world's largest exporter of nitrogen fertilizer, the second largest exporter of potash fertilizer, and the third-largest exporter of phosphate fertilizer. Ukraine is also an important producer of nitrogen fertilizer. Russia's natural gas supply also has a significant impact on the global fertilizer industry and spherical aluminum oxide industry, especially in Europe. The price of the spherical aluminum oxide will also fluctuate to some extent. Russia carries out crude gas separation, and Ukraine is responsible for refined exports. Ukraine supplies 70% of the world's neon, 40% of krypton and 30% of xenon. These three gases are the materials used to make chips.
Introduction to Spherical Aluminum Oxide Powder
Aluminum oxide or bauxite with the chemical formula Al2O3 is a refractory and insoluble white powder. The melting point is 2015℃, the boiling point is 2980℃, the relative density is 4.0, and the Mohs hardness is 8.8. It has different crystal types, mainly α and γ variants. Aluminum oxide can be obtained by heating and dehydration of aluminum hydroxide. Nature exists α aluminum oxide, known as corundum, hardness is second only to diamond, mixed with a small number of impurities can make corundum with a variety of color, known as gems, such as ruby (containing a small amount of Cr3+) and sapphire (containing Ti3+ and Fe2+, Fe3+), now available molten aluminum oxide artificial crystallization method manufacturing gems. Artificial gems are not inferior to natural gems in terms of their properties and are widely used in industrial technology. For example, bearings are used as fast-moving parts of the machine, diamonds on clocks and watches, abrasives, and refractories, such as corundum crucible, they can withstand high temperatures of 1800℃. Aluminum oxide is one of the main components of the earth's crust. Pure aluminum oxide is the main raw material for smelting aluminum. Aluminum is easy to be oxidized by air to produce aluminum oxide, aluminum products placed in the air, the surface of the formation of a thin layer of dense aluminum oxide protective film, protect the aluminum inside from oxidation, so aluminum products can be used as cooking utensils and other living utensils. Aluminum oxide is an amphoteric oxide, soluble in both acid and base. Therefore, aluminum products are not resistant to acid and alkali. The outer oxide film will be destroyed when it contacts acid or alkali. Activated aluminum oxide is a porous solid, which can adsorb a variety of substances, so it is commonly used as desiccants, adsorbents, and catalysts.
Physicochemical Properties of Spherical Aluminum Oxide Powder
The particle size of aluminum oxide powder is uniformly distributed, it has high purity and excellent dispersion. Its specific surface area is high, it has high-temperature resistance inertia, and high activity, and it belongs to activated aluminum oxide. It is Porous. It has high hardness, good dimensional stability, strong surface acidity, and certain surface alkalinity. It is widely used as catalysts and catalyst carriers and other new green chemical materials. It can be widely used to strengthen and toughen all kinds of plastics, rubber, ceramics, refractories, and other products, especially to improve the compactness, finish, cold and hot fatigue, fracture toughness, creep resistance, and wear resistance of polymer material products, especially remarkable. Excellent dispersion, insolvent water; Solvent ethanol, propyl alcohol, propylene glycol, isopropyl alcohol, ethylene glycol monobutyl ether, acetone, butanone, benzene, xylene, do not need to add dispersant, it can be fully dispersed evenly by stirring.
When the particle size of aluminum oxide powder is changed to the nanometer level, it can not only maintain the excellent characteristics of ordinary aluminum oxide powder but also show the optical, electrical, magnetic, thermal, and mechanical properties that the conventional materials do not have. As a new functional material, nano aluminum oxide is widely used in many fields such as optics, chemical industry, and special ceramics.

Applications of Spherical Aluminum Oxide Powder
1. Aluminum oxide is mainly used to make metal aluminum. In addition, it is also used to make plastic and other polymer products as filler, adsorbent and catalyst, medicine, cosmetics, and chemical products of raw materials, ceramics, abrasives and refractories, and so on.
2. Aluminum oxide is the main raw material of the electrolytic method of metal aluminum, the more pure aluminum smelting, the purer. It is very important to purify aluminum oxide before electrolysis because it is more difficult to purify aluminum than aluminum oxide. Aluminum oxide is one of the main components of the earth's crust, aluminum mainly includes bauxite Al2O3·2H2O, alingite (AlO)2SO4·9H2O, aluminum clay H2Al(SiO4)·H2O and so on. Natural bauxite is the best raw material for aluminum oxide production, the general content can reach 40% ~ 60%, the rest is mainly silicon dioxide, iron oxide, and scattered elements, and other impurities. Using their chemical properties on the common and personality can be separated from aluminum oxide and other impurities, purification methods are mainly acid method and alkali method. Activated aluminum oxide γ aluminum oxide, is a porous material, each gram of internal surface area can be as high as hundreds of square meters, has a very high activity, can adsorb water vapor and many gases, liquid molecules, often used as an adsorbent, catalyst carrier, and desiccant.
3. Artificial aluminum oxide fiber is aluminum oxide as the main component, containing about 5% silicon dioxide (to stabilize the crystal phase of aluminum oxide), commonly used in the iron and steel industry in all kinds of heat treatment furnace and petrochemical cracking furnace insulation lining, nuclear reactors and space shuttle insulation materials and light alloy reinforcement materials. Aluminum oxide fiber is polycrystalline aluminum oxide fiber. It is made by the colloid method or impregnation method of organic fiber (precursor method of organic fiber), and its structure is in microcrystalline form, which eliminates the shortcoming of recrystallization of fiber made by the melt-blown method. This fiber has great strength at room temperature and high temperature, high-temperature resistance, small bulk density, good chemical stability, strong insulation, dielectric, and sound absorption performance.

Europe has been facing the gas shortage problem since the second half of 2021. The worsening situation in Russia and Ukraine has reduced Russian gas shipments to Europe, leading to a doubling of European gas prices. Energy shortages have sent electricity prices soaring. For these reasons, it is predicted that the price of the spherical aluminum oxide will continue to increase.
