High Purity Spherical Aluminum Oxide Al2O3 Powder CAS 1344-28-1,99.9%

The biggest immediate challenge for the EU will be replenishing its depleted gas inventories. While the EU could still increase LNG imports from countries such as the US, such purchases would be more expensive.
Refilling natural gas storage space to historical average levels this year could cost 70 billion euros, a sevenfold increase, compared to 10 billion euros in previous years. "
A complete replacement for Russian gas is not only very expensive, but it also may not be possible.
In the next 12 months, there is little way to meet the demand for a "normal" year in the absence of Gazprom, which also includes spherical Al2O3 powder.

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.
