What is aluminum oxide used for?

Aluminum oxide overview

The molecular formula of alumina is Al2O3. The alumina molar mass is 101.96 g/mol. Al2O3 is an electrical insulator that has a fairly high thermal conductivity to ceramic materials. The most common form of crystalline alumina is called corundum. Alumina is available in activated, hyperactivated, acidic, basic and neutral grades and in flash grade, TLC, biomass purification, decolorization, dioxin analysis, PCB removal, pyrogen removal and biotech macroporous forms.

Aluminum oxidation is what makes aluminum corrosion resistant. Aluminum has a high affinity for oxygen. When a new aluminum surface is exposed to air or any other oxidizing agent, it rapidly forms a thin, hard film of aluminum oxide.

Oxides do not conduct electricity. However, certain oxides of perovskite structure are conductive in cathodes of solid oxide fuel cells and oxygen generation systems. They are compounds containing at least one oxyanion and one metal cation. They are generally insoluble in aqueous solutions (water) and are very stable, making them useful in ceramic structures such as alumina ceramics bowls for the production of advanced electronics, and lightweight structural components for aerospace and electrochemical applications such as fuel cells.

Exhibits ionic conductivity. Metal oxides are basic acid anhydrides and thus can react with acids and strong reducing agents in redox reactions. Reactive chromatography grade alumina is used in illumination, photochromatography and various chromatographic separation techniques.

Alumina is usually available in large quantities immediately. High purity, submicron and nanopowder forms are contemplated. Alumina can also be made into granules, pellets, powders, sputtering targets, tablets and nanopowders. Typical and custom packages are available, along with other research, technical and safety (MSDS) data.

Application of aluminum oxide

Most of the alumina produced is used to form metallic aluminum. Oxygen typically reacts with metallic aluminum to catalyze corrosion. However, when combined with oxygen to form aluminum oxide, it forms a protective coating and prevents further oxidation. This adds strength and makes the material less prone to deterioration. Alumina is mainly used as analytical reagents, dehydration of organic solvents, adsorbents, organic reaction catalysts, abrasives, polishing agents, raw materials for aluminum smelting, refractory materials, etc.

Industries that use alumina include:

Medical profession

Due to its hardness, biological inertia and chemical properties, alumina is the material of choice for bearings in hip replacements such as prosthetics, bionic implants, prosthetic eye replacements, tissue augmentations, crowns, abutments, bridges and other dental implants in. It is also used in laboratory equipment and tools such as crucibles, furnaces and other laboratory utensils.

 Military and Protective Equipment

Alumina's strength and lightweight properties help enhance bulletproof vests, such as breastplates, as well as vehicle and aircraft armor, which are its largest markets. Alumina is also used in synthetic sapphire bulletproof windows and ballistics.

 Electronic and electrical industry

Its high melting and boiling points, as well as its excellent heat resistance, make alumina an ideal material for making high temperature furnace insulation and electrical insulators. Alumina thin films are also an important part of the microchip industry. Some of its other uses include spark plug insulators, microelectronic substrates, and insulating heat sinks.

 Gem industry

Alumina is a precious element that forms rubies and sapphires. Its crystalline form, corundum, is the basic element of these precious gems. The deep red color of rubies is attributed to chromium impurities, while the different colors of sapphires come from traces of iron and titanium.

 Industrial application

Because alumina is chemically inert, it is used as a filler for plastics, bricks, and other heavy clay utensils such as kilns. Due to its high strength and hardness, it is often used as an abrasive for sandpaper. It is also an economical alternative to industrial diamonds.

Alumina is also used to produce piping components such as elbows, tees, straight pipes, hydrocyclones, reducers, nozzles and valves. Other applications include the production of various machining tools, cutting tools, thermocouple sheaths, wear resistant pump impellers and baffles.
