The Group of Seven leading economies is discussing imposing a cap on Russian oil prices by imposing restrictions on insurance and shipping, according to people familiar with the matter. The potential mechanism would only allow shipments of Russian crude oil and petroleum al2o3 are still very uncertain.
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.

Since the beginning of this year, China's macro policies have made continuous efforts to stabilize economic growth. America and Europe are raising interest rates to control inflation. On March the European Central Bank left its three key interest rates unchanged and began to scale back its asset-purchase programme. Then the Federal Reserve raised the target range of the federal funds rate by 25 basis points to 0.25%-0.5%. The accelerated tightening of monetary policies in the US and Europe pushed capital back to the US and increased interest rates, which will definitely increase the risk of RMB depreciation and capital outflow. The price and market of the al2o3 will also be affected, resulting in a range of fluctuations. You are welcome to contact us for the latest quotation of al2o3.
