What is alumina used for?
The US President recently said the conflict between Russia and Ukraine had driven up the prices of all the world's major food staples, including wheat, corn, barley, oilseeds and edible oils, and that Russia and Ukraine together supplied more than 25% of the world's wheat exports and about 20% of its barley exports.
To address the food shortage, the Biden administration says it plans to increase the number of counties eligible for insurance for double cropping. Double cropping is when farmers grow two different crops a year on the same field.
Under Biden's plan, the number of counties eligible for two-season crop insurance would increase by 681, for a total of 1,935.
The UN has warned that up to 1.7bn people are "highly exposed" to the domino effect of the conflict between Russia and Ukraine on the global food, energy, and financial systems. The agency says conflict could increase hunger in countries where people are already suffering from malnutrition.
Even countries where food is less scarce are being hit by rising prices. U.S. grocery prices rose 1% in April, compared with a 10.8% increase over the past 12 months, the Labor Department said recently.
According to the White House, global food prices have risen nearly 13 percent since the outbreak of the Russia-Ukraine conflict.
Besides, affected by the ever-changing international situation, the supply and prices of international bulk al2o3 powder are still very uncertain.
High temperature resistance: alumina can be used in oxidation and reduction atmospheres up to 1650°C (2900°F) and in vacuum environments up to 2000°C (3600°F).
Wear resistance: alumina is a very hard ceramic with excellent wear resistance. It is an ideal choice for wear-resistant inserts or products.
Electrical insulators: alumina is commonly used as high temperature electrical insulators, especially for higher purity grades that provide better resistivity.
Chemical resistance: alumina has good resistance to strong acids and bases at high temperature, so it is an ideal choice for applications that need to resist corrosive substances.
High compressive strength.
High mechanical strength.
Resist strong acid and alkali at high temperature.
Excellent electrical insulation performance.
Good thermal conductivity.
What are the advantages of alumina?
Alumina is a kind of wear-resistant advanced technology ceramic material, which is often used in various industrial applications. It has high hardness and wear resistance, low erosion level, high temperature resistance, corrosion resistance and biological inertia. In addition, it can be highly polished, making it suitable for precision sealing applications such as pumps and pistons. Alumina has become an excellent high temperature ceramic material because of its high temperature stability. It is the most commonly used type of advanced ceramics with a purity of 95-99.9%.

Some common applications of alumina include:
Electronic components and substrates.
High temperature electrical insulator.
High voltage insulator.
Precision axles and axles in high wear environment.
Roller and ball bearings.
Shot peening nozzle.
Hose head plate.
Wires and conductors.

On August 1, the European Union officially began to implement the "voluntary reduction" agreement on natural gas adopted last month. Under the agreement, EU member states will reduce gas demand by 15 per cent from the average consumption over the past five years through measures of their choice between August 1 this year and March 31 next year.
Several major German cities, such as Berlin, Hanover and Munich, have begun to take measures to reduce energy consumption. Berlin, for example, decided to turn off the lights of more than 200 tourist attractions at night. Berlin's municipal buildings will have indoor temperatures of no more than 20 degrees Celsius between October 1 and March 31 next year, and only nurseries, schools, nursing homes and hospitals can be exempted from energy-saving measures.
Spain's energy conservation plan forces companies, businesses and vehicles to limit air-conditioning temperatures in summer and heating temperatures in winter. The above-mentioned places must limit the air-conditioning temperature to more than 27 degrees Celsius in summer and the heating temperature below 19 degrees Celsius in winter. The plan requires that shop window lighting be turned off at 22:00. The plan also requires the administration to regularly review the heating systems of enterprises in order to avoid energy waste.
