What is the use of aluminum oxide?
Because of its hardness, bioinertia and chemical properties, alumina is the preferred material for hip replacement bearings, such as prosthetics, bionic implants, prosthetic eye substitutes, tissue reinforcements, crowns, abutments, bridges and other dental implants. It is also used in laboratory equipment and tools, such as crucibles, furnaces and other laboratory appliances.
Military and protective equipment
The strength and lightweight properties of alumina help enhance bulletproof vests, such as breastplate, as well as vehicle and aircraft armor, which is its largest market. Alumina is also used in synthetic sapphire bulletproof windows and ballistics.
Electrical and electronic industry
Its high melting point and boiling point, as well as excellent heat resistance, make alumina an ideal material for making insulation and electrical insulators for high temperature furnaces. Alumina film is also an important part of the microchip industry. Some of its other uses include spark plug insulators, microelectronic substrates and insulated radiators.
Alumina is a valuable element for the formation of rubies and sapphires. Its crystalline form corundum is the basic element of these precious gems. The deep red color of the ruby is attributed to chromium impurities, while the different colors of the sapphire come from traces of iron and titanium.
Because alumina is chemically inert, it is used as a filler for plastics, bricks and other heavy clay utensils such as kilns. Because of its high strength and hardness, it is often used as an abrasive for sandpaper. It is also an economic substitute for industrial diamonds.
Alumina is also used in the production of pipe components such as elbows, tees, straight pipes, hydrocyclones, reducers, nozzles and valves. Other applications include the production of various machining tools, cutting tools, thermocouple jackets, wear-resistant pump impellers and baffles.
How strong is aluminum oxide?
Alumina has a Morse scale of 9, and the only natural materials that can scratch alumina are diamond and Mo stone.
Does aluminum oxide react with water?
Alumina is almost insoluble in water.
What are the advantages of aluminum oxide?
Alumina 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 alumina is, the higher the resistance is.
Alumina 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.
Alumina has excellent chemical stability and high corrosion resistance.
Alumina is slightly soluble in strong acids (such as hot sulfuric acid and hot HCl and HF) and alkaline solutions, but insoluble in water. Pure alumina can resist chemical corrosion, which makes pure alumina 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.
Alumina ceramics have the lowest steam and decomposition pressure.
