Russian President says if the European Union imposes an oil embargo, Europe will buy energy at the most expensive price and economic activity in Europe will weaken. Rosneft needs to change its business model. Russia will help facilitate settlement and access to loans and insurance in its own currency.
According to Reuters, the European Commission will unveil a 210 billion euro plan on how Europe can end its dependence on Russian fossil fuels by 2027 and use its distance from Moscow to accelerate a shift to green energy. According to a draft document seen by Reuters, Brussels will propose a three-pronged plan to wean countries off Russian fuel: switch to importing more non-Russian gas, move more quickly to promote renewable energy, and work harder to conserve energy. The draft measures, which include EU law, non-binding plans, and possible recommendations by national governments, are subject to change before publication.
Austria is not a member of NATO and will not seek membership in the future, the Austrian Foreign Minister said in Brussels recently. He stressed that it was "their choice" for Sweden and Finland to seek NATO membership, while Austria would remain neutral.
The supply and prices of many other al2o3 are expected to continue to be influenced by international situations.
What is aluminum oxide ceramic?
Aluminum oxide ceramic, also known as alumina ceramic or aluminum oxide Al2O3 is an industrial oxide ceramic, which is famous for its high hardness and high thermal conductivity. The characteristics of aluminum oxide ceramics make it one of the most widely used ceramics in structure, wear and corrosion environment.
Aluminum oxide ceramics are usually made of bauxite and can be formed by injection molding, molding, isostatic pressing, grouting, diamond processing and extrusion. Like aluminum nitride and other important engineering materials, aluminum oxide can be produced by dry pressing and sintering or hot pressing with appropriate sintering aids.
Aluminum oxide-based ceramics is one of the most advanced ceramic materials known to be studied and characterized. Because of the important combination of attributes, their behavior has been thoroughly studied. Aluminum oxide is characterized by high hardness, corrosion resistance, good thermal stability, good dielectric properties (used for frequency conversion from DC to GHz), low loss tangent and stiffness.
Aluminum oxide ceramics Properties:
According to Al2O3 content, aluminum oxide can be divided into 75% aluminum oxide, 85% aluminum oxide, 95% aluminum oxide, 99% aluminum oxide and so on.
According to the crystal phase, there are mullite, corundum-mullite, corundum.
According to the types of additives used, there are chromium corundum, titanium corundum and so on.
Aluminum oxide is an excellent electrical insulator, which can resist extremely high current, and its electrical resistance increases with the increase of its purity. The higher the purity of aluminum oxide is, the higher the resistance is.
Aluminum oxide has a very high melting point and strong mechanical strength. However, when the temperature exceeds 1000 degrees Celsius, its mechanical strength decreases. Because of its great difference in thermal expansion coefficient, its thermal shock resistance is not very effective when exposed to very high temperatures.
The excellent chemical stability of aluminum oxide is the main reason for its high corrosion resistance.
Aluminum oxide is also slightly soluble in strong acids (such as hot sulfuric acid and hot HCl and HF) and alkaline solutions, but insoluble in water. Pure aluminum oxide can resist chemical corrosion, which makes pure aluminum oxide become the main choice of engineering components in many industrial applications. Its resistance to chemical corrosion has been proved to be due to its low solubility in these chemicals.
The introduction of additives can enhance the physical and chemical properties of aluminum oxide. These additives combined with different production processes can help to produce aluminum oxide ceramics of different sizes and shapes.
Aluminum oxide ceramics have the lowest steam and decomposition pressure.
Aluminum oxide uses:
Aluminum oxide ceramics are widely used in acid-resistant pump impellers, pump bodies, acid-carrying pipe linings and valves because of their excellent chemical stability.
Aluminum oxide ceramics are used in the manufacture of textile wear-resistant parts and cutting tools. This is due to their high hardness and wear resistance.
Aluminum oxide ceramic materials are used to make spark plugs and can be used in all kinds of engines.
Transparent aluminum oxide ceramics are used to make high pressure sodium lamp and infrared detection window materials.
Aluminum oxide ceramics with aluminum oxide content higher than 95% can be used as excellent electrical insulators. They also have low dielectric loss and are widely used in electronics and electrical appliances.
Transparent aluminum oxide shows good permeability to visible light and infrared light.
Other important applications of aluminum oxide ceramics can be found in sealing rings, medical prosthetics, laser tubes, thermocouple tubes, electronic substrates, bulletproof armor, electrical insulators, grinding media and wear parts.

With Russia taking the lead on Poland and Bulgaria at the end of last month, there appears to be a growing sense of compromise within the EU over whether to accept Moscow's proposed rouble settlement order.
Italy's prime minister said recently that European companies would be able to buy gas in roubles without violating sanctions. This apparently ignores the guidance of hardliners in the EU to "fight to the end".
For weeks, European companies have been trying to find ways to meet Russia's payment demands for the rouble while maintaining vital gas supplies without violating sanctions against Moscow.
Late last month, European Commission President Von der Leyen said operating under the mechanism would violate sanctions and asked European companies not to bow to Russian demands. However, the EU has yet to issue more rigorous written guidelines on how companies should pay Gazprom.
The Italian prime minister said recently, "There is no official announcement from the European Union about what ruble settlement means for sanctions violations, and no one has said whether ruble payments violate sanctions or not. It's a grey area."
"In fact, most gas importers are already opening rouble accounts for deals with Gazprom,"
He also used German companies as a shield. He said Germany's largest gas importer had already paid in rubles. "In fact, we saw evidence yesterday that the largest gas importer in Germany has already paid in rubles."
