Introduction toSpherical Al Oxide Powder

Aluminum oxide



Al2O3 is a white powder that is insoluble and refractory. It has a melting point of 2015, a boiling point of 2980, a relative density of 4.0, and possesses 8.5 Mohs hardness. It comes in a variety of crystal types, with the most common being a- and g varieties. Aluminum oxide is made by heating aluminum hydroxide and dehydrating it. Aluminum oxide is found in nature. This aluminum oxide is known as corundum. A small number of impurities can create corundum with a variety color. Artificial gems can be used in industrial technology and are comparable to natural gems in terms their properties. Bearings are used for fast moving parts, like diamonds on watches and clocks. Abrasives and refractories such as corundumcrucible can also be used. They can withstand high temperatures up to 1800F. Aluminum oxide is one main component of the earth’s crust. Pure aluminum oxide is used as the raw material to make aluminum. Aluminum oxide is easily oxidized by oxygen to make aluminum oxide. Aluminium products placed in the atmosphere will form a thin protective layer of aluminum oxide that protects the aluminum inside. These aluminum products can then be used to cook and use other living utensils. Aluminum oxide, an amphoteric ore, is soluble in both acids and bases. Aluminum products aren’t resistant to acid and alkali. Contact with acid or alkali will cause the outer oxide layer to be destroyed. Activated aluminiu oxide is a porous material that can adsorb many substances. This is why it is often used as desiccants or adsorbents and catalysts.

Physical Properties of Spherical Al Oxide Powder

The particle size

aluminum oxide

Powder is uniformly distributed. It has excellent dispersion and high purity. It is a powder with a large specific area. It also has high-temperature resistance and inertia. It is Porous. It has high hardness and good dimensional stability. It is often used in the production of catalysts, catalyst carriers, and other green chemical substances. It can be used to strengthen and toughen many types of plastics. Excellent dispersion, insolvent waters; Solvent alcohol, propylalcool, propylenegl, isopropylalcool, ethylene glycol monobutylether, acetone and benzene.

The particle size of aluminum oxide powder can be changed to the

nanometer level

This material can not only retain the exceptional characteristics of regular aluminum oxide powder but also exhibits the optical, electrical and magnetic properties, as well as the mechanical properties, that traditional materials don’t have. Nano aluminum oxide is a novel functional material and is used in many fields, such as optics, chemical industries, and special ceramics.

Spherical Aluminum Oxide Powder Applications

1. Aluminum oxide is the main ingredient in making aluminum. Aluminum oxide is used primarily to make aluminum.

2. Aluminum oxide is the primary raw material for the electrolytic method to metal aluminum. The purer aluminum smelting process, the better. Aluminum oxide is easier to purify than aluminum dioxide. Aluminum oxide is one main component of the earth’s crust. This includes aluminum oxide Al2O3*2H2O (Alingite)2SO4*9H2O as well as aluminum clay H2Al(SiO4)*H2O). Natural bauxite, which can be found in the range of 40% to 60%, is the best raw material used for the production of aluminum oxide. The rest is made up mainly from silicon dioxide, ironoxide, and scattered elements. You can separate aluminum oxide from the other impurities by using their chemical properties. The main purification methods are the acid method and the alkali method. Activated aluminiu oxide g aluminum dioxide, a porous metal, each gram can have as many as hundreds of meters of internal surface area, has a high activity, can absorb water vapour and many gases, liquid molecules and is often used as an agent, catalyst carrier and desiccant.

3. Artificial aluminum dioxide fiber is an aluminum oxide main component. It contains approximately 5% silicon dioxide to stabilize the crystal phase. This fiber is commonly used in the iron-and-steel industry in all types of heat treatment furnaces and petrochemical cracking oven insulation linings, nuclear reactors and spaceship insulation materials and light weight reinforcement materials. Aluminum oxide fiber is a polycrystalline aluminum dioxide fiber. This fiber is made using the impregnation (colloid) method of making organic fiber. Its structure is microcrystalline, which eliminates recrystallization problems in fiber made with the melt-blown process. This fiber exhibits great strength at both high and low temperatures, as well as high resistance to high-temperature and high temperatures.
