Gazprom recently said it had completely suspended gas supplies to Bulgarian Gas company and Polish Oil and Gas Company (PGNiG) because it was not being paid in rubles. Russia said it would resume gas supplies after it agreed to pay for them in rubles.
Bulgaria and Poland announced Monday that they have received a notice from Russia to suspend natural gas supplies from Monday.
Russian President Vladimir Putin on March 31 signed a presidential decree to settle gas trade with "unfriendly" countries and regions in rubles. When the new rules took effect on April 1, Presidential press secretary Dmitry Peskov said Russia would not immediately "cut off gas" to Europe, as the cost of gas supplies starting April 1 should be settled in the second half of April or May.
Because of the ever-changing international situation, the supply and prices of international bulk spherical Al2O3 powder are still very uncertain.
About Spherical Aluminum Oxide Al2O3 Powder:
Spherical Aluminum Oxide has excellent mechanical properties and is often used as a grinding medium in various mills. Spherical Aluminum Oxide has high compressive strength and wears resistance. Spherical Aluminum Oxide has high filling property, and its particles have a high Spherical rate and wide particle size distribution. It can fill rubber and plastic with high density to obtain a mixture with low viscosity and good fluidity.
Secondly, the spherical oxidation furnace also has high thermal conductivity. Because it can be filled with high density, compared with crystalline silicon powder, a mixture with high thermal conductivity and good heat dissipation can be obtained.
Is aluminum oxide safe for skin? Although aluminum oxide is certainly abrasive, it is also a skin irritant with a very questionable safety record. In any case, it is unquestionably unpleasant. Aluminum oxide crystals inflame and irritate the skin, leaving it red, whereas, baking soda crystals have a natural ability to calm, tone and soothe the skin. Is aluminum oxide safe to breathe? Aluminum oxides rank amongst the less toxic substances and only exhibit toxic effects in high concentrations. Inhalation of aluminum oxide dust should be avoided, but there is no evidence of significant harm to the lungs associated with the inhalation of aluminum oxide dust.
Spherical Aluminum Oxide also has low wear resistance. Because of its spherical appearance, the wear of the mixer, molding machine and mold and other equipment is greatly reduced, and the service life of the equipment can be extended. TRUNNANO is a trusted global Spherical Aluminum Oxide Al2O3 Powder supplier. Feel free to send an inquiry about the latest price of Spherical Aluminum Oxide at any time.
Performance of Spherical Aluminum Oxide Al2O3 Powder：
1. High filling density: With its large particle diameter and broad particle size distribution, realizes high-density filling for rubber and plastic and produces compounds with low viscosity and good fluidity.
2. High thermal conductivity: High filling density enables the production of compounds with higher thermal conductivity and higher heat dissipation rate compared to crystalline silica.
3. Low abrasivity: Due to its Spherical shape, less-wearing of kneading machines, forming machines and dies.
Technical Parameter of Spherical Aluminum Oxide Al2O3 Powder：
|Test Items||Unit||Typical value||Test Method|
|Ionic Impurities||Na+||ppm||56.3||Atomic Absorption Spectrometer|
|Cl-||ppm||1.4||Auto Electric Potential Titrator|
How is Spherical Aluminum Oxide Al2O3 Powder produced?
Spherical Aluminum Oxide, which is produced by the high-temperature melt-injection method, has a high Spherical rate and high α-phase alumina content and has excellent performance when used as filler for rubber and plastics and as raw material for ceramics.
Applications of Spherical Aluminum Oxide Al2O3 Powder:
Spherical Aluminum Oxide has a wide range of functions:
1. Coating: ceramic coating, wear-resistant coating, plasma spraying.
2. Ceramics: transparent ceramics, biological ceramics, alumina ceramics.
3. Petrochemical industry: high-efficiency catalyst, catalyst carrier, automobile exhaust purification materials.
4. Polishing materials: submicron/nanometer abrasive, monocrystalline silicon wafer grinding, precision polishing materials.
5. Lighting: long afterglow phosphor raw materials and rare earth tricolor phosphor materials, high-pressure sodium lamp tubes, LED lamps, etc.
6. Electronics: integrated circuit substrates, single-crystal materials, far infrared materials.
7. Cosmetics: cosmetic fillers.
8. Inorganic membrane materials.
Storage Condition of Spherical Aluminum Oxide Al2O3 Powder:
Spherical Aluminum Oxide Al2O3 Powder should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition, should avoid the heavy pressure, according to ordinary goods transportation.
Packing & Shipping of Spherical Aluminum Oxide Al2O3 Powder:
It is packed in double plastic bags inside, which can be filled with argon in a vacuum; it can be vacuumed and filled with argon for protection.
Spherical Aluminum Oxide Al2O3 Powder packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Spherical Aluminum Oxide Al2O3 Powder shipping: could be shipped out by sea, by air, by express as soon as possible once payment receipt.

Aluminum Oxide Health & Safety Information
Russia's Rokot-M carrier rocket is scheduled to launch for the first time in 2024.
The first launch of the Rokot-M carrier rocket is planned for 2024 from the Plesetsk cosmodrome, the general manager of the Khrunichev National Space Research and Production Center told TASS. The Rokot-M, a lightweight carrier rocket powered by liquid fuel, began development in 2018, with The Russian side using domestic components instead of Ukrainian components.
