Hasad Foods, the agricultural investment arm of Qatar's sovereign wealth fund, said the government would increase its grain reserves from 250,000 tons to 300,000 tons in the near future, which is enough to feed the population for six months.
With a lot of deserts, Qatar suffers from water shortages, and Qatar depends on food imports for a long time. Recently, the ongoing tension in Ukraine has caused global food supply tension and rising prices.
In addition to that, the geopolitical situation also affects the supply and prices of many commodities like the 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.
Technical Parameter of Spherical Aluminum Oxide Al2O3 Powder：

Aluminum Oxide Health & Safety Information
Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.
The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.
Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.
"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.
Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.
Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.
Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the spherical Al2O3 powder will be influenced by that.
