What is Alox Aluminum Oxide?

Alox Aluminum Oxide, commonly known as bauxite, has a chemical formula of Al2O3, a white powder that is refractory and insoluble in water. The melting point is 2015°C, the boiling point is 2980°C, the relative density is 4.0, and the Mohs hardness is 8.8. With different crystal forms, there are mainly two variants of α and γ. Alox Aluminum Oxide can be obtained by heating and dehydrating aluminum hydroxide. The α-type alumina that exists in nature is called corundum. Its hardness is second only to diamond. A small amount of impurities can make corundum have various colors. It is called gemstone, such as ruby ​​(containing a small amount of Cr3+) and sapphire (containing Ti3+ and Fe2+ , Fe3+), gemstones can now be manufactured by artificial crystallization of fused alumina. Artificial gemstones are not inferior to natural gemstones according to their properties, and are widely used in industrial technology. For example, it is used as the bearing of the fast rotating part of the machine, the diamonds and abrasives on the watch, the refractory material, and the corundum crucible, which can withstand the high temperature of 1800 ℃.

Alox Aluminum Oxide is one of the main components of the earth’s crust. Pure alumina is the main raw material for smelting aluminum. Aluminum is easily oxidized by air to form alumina. When aluminum products are placed in the air, a thin layer of dense aluminum oxide protective film is formed on the surface to protect the aluminum inside from being oxidized. Therefore, aluminum products can be used as cooking utensils and other living utensils. Alox Aluminum Oxide is an amphoteric oxide, soluble in both acid and alkali. Therefore, aluminum products are not resistant to acid and alkali. When encountering acid or alkali, the oxide film on the outer layer will be destroyed.

Activated alumina is a porous solid that can adsorb a variety of substances and is often used as a desiccant, adsorbent and catalyst.

Alox Aluminum Oxide Uses

1. The diversification of Alox Light weight aluminum Oxide’s homes makes it commonly utilized, however greater than 90% of it is made use of to prepare metal aluminum, et cetera is utilized as fillers for plastics and other polymer items, adsorbents as well as catalysts, medications, cosmetics as well as Raw materials for chemical products, ceramics, abrasives as well as refractory products, and so on. It is traditional in China to call it unique alumina or multi-variety alumina. Its selections and requirements have a growing pattern.

2. Alox Aluminum Oxide is the main basic material for electrolytic light weight aluminum manufacturing. The purer the alumina made use of, the purer the aluminum generated. Considering that it is more difficult to cleanse light weight aluminum than alumina, the purification of alumina before electrolysis is really essential. Alox Light weight aluminum Oxide is just one of the major parts of the planet’s crust. Light weight aluminum ores mainly include bauxite Al2O3 · 2H2O, alunite (AlO)2SO4 · 9H2O, light weight aluminum clay H2Al(SiO4) · H2O, etc my nation’s light weight aluminum ore resources are really rich, such as Taiwan, Shandong, Shanxi, Guizhou, Kunming, Hebei, Henan, Liaoning and also various other locations have huge books. All-natural bauxite is the very best basic material for creating alumina, the basic content can reach 40% to 60%, et cetera is primarily pollutants such as silica, iron oxide and scattered elements. Alox Aluminum Oxide can be divided from various other contaminations by using the commonality and originality of their chemical properties. The filtration methods primarily include acid approach and antacid approach. Activated alumina is γ-type alumina. It is a porous material with an inner surface of approximately hundreds of square meters per gram. It has exceptionally high activity as well as can take in water vapor and lots of gas as well as liquid particles. It is frequently used as an adsorbent and catalyst service provider. and desiccant.

3. The man-made Alox Light weight aluminum Oxide fiber is mostly made up of Alox Aluminum Oxide as well as consists of about 5% silica (used to stabilize the crystal phase of alumina). It is typically made use of in different warmth therapy furnaces in the steel market and in petrochemical industries. Insulation heater cellular linings for breaking furnaces, heat insulation materials for atomic power plants and space shuttles, and reinforcement products for light alloys, and so on. Alumina fiber is polycrystalline alumina fiber. It is manufactured by colloidal approach or natural fiber impregnation technique (natural fiber forerunner approach), and also its framework remains in the type of microcrystalline, which gets rid of the downside of recrystallization as well as pulverization of fibers made by thaw blowing method. This kind of fiber has fantastic strength at area temperature level and also heat, heat resistance, small mass thickness, good chemical stability, solid warm conservation, outstanding dielectric and also audio absorption residential or commercial properties, and so on.

4.Alox Aluminum Oxide is used in cosmetics such as creams, blushers, foundations, lipsticks and face washes. It also acts as an insoluble carrier for mineral pigments and is mixed into mineral powder cosmetics.

Production Method of Alox Aluminum Oxide

Its preparation methods include acid method, alkali method and aluminum alcohol method. At present, the alkali method is mainly used in China, and a few manufacturers use the aluminum alcohol method. Acid method Make aluminum sulfate into a 6% aqueous solution, add it to the neutralization tank, then make liquid ammonia into 15%-20% ammonia water, quickly add ammonia water according to the calculated amount, and react at room temperature for 40-60 minutes under strong stirring , when the pH value reaches about 8-9, the reaction is basically completed. The resulting precipitate is filtered and washed with deionized water to remove impurity ions. Generally, a small amount of ammonia water is added to the washing water to adjust the pH value to 8-9 to prevent material loss caused by the gelling process of aluminum hydroxide during the washing process. Add a small amount of 33% nitric acid solution to the washed precipitate to form a colloidal slurry under strong stirring (this process is called beating). After spray-drying, the obtained microspherical aluminum hydroxide is extruded and activated at 550°C for 4 hours, that is, dehydrated to form activated alumina.
Its A12(SO4)3+6NH3?H2O→2AI(OH)3↓+3(NH4)2SO42AI(OH)3→A12O3+3H2O
Alkali method Add water to industrial solid caustic soda to make a caustic soda solution with a concentration of 600g/L, add aluminum hydroxide at 50-80°C, heat up to 110°C, keep warm for 3 hours to react, and dilute the obtained solution with water to contain 100g of alumina /L, stand still for 0.5-1h, filter to remove insoluble impurities such as ferric hydroxide, then neutralize the clear liquid and 20% nitric acid solution according to a certain ratio, control the temperature at 30-50°C, and control the pH 7-7.5 After reacting for about 10 minutes, the reaction solution was aged for 2 hours under stirring at room temperature, filtered, washed with deionized water several times, dried at 110°C, extruded, dried, and activated at 500°C for 4 hours to obtain active Alox Aluminum Oxide. Its AI(OH)3+NaOH→NaAIO2+2H2O
Aluminum Alcohol Method Add metal aluminum flakes to isopropanol solution for reaction to produce aluminum isopropoxide, and bubbling with water vapor (inlet temperature 180°C, hydrolysis temperature 175°C) to hydrolyze aluminum isopropoxide to produce hydrated alumina , after ripening, filtering, drying at 100°C and dehydration at 500°C to activate Alox Aluminum Oxide. Its Al+3(CH3)2CHOH→(C3H7O)3AI+H2↑

Chemical Activity of Alox Aluminum Oxide

The chemical activity of colloidal aluminum hydroxide decreases significantly with the increase of its lattice energy, and the chemical activity of γ series compounds is much greater than that of α series isomers. Corundum is an inert compound, which is not corroded by strong acid and strong alkali even at a temperature of 573K, and has a high melting point (2326K) and a Mohs hardness as high as 9.
Alox Aluminum Oxide and aluminum hydroxide are practically insoluble in water, but soluble in acid and alkali solutions, and are typical amphoteric compounds. Their alkalinity and acidity are weak, and only the aluminum salt solution of strong acid is very stable and not hydrolyzed. Therefore, inorganic acids such as sulfuric acid, hydrochloric acid or nitric acid can be used to decompose aluminum ore to obtain the corresponding aluminum salt solution to produce alumina. Alox Aluminum Oxide and aluminum hydroxide are dissolved in caustic solution to produce aluminate solution. They react with alkali metal or alkaline earth metal oxides at high temperature to give various aluminates. Its sodium, potassium, and barium salts can be directly dissolved in water, while calcium aluminate can be transformed into sodium aluminate solution after reacting with sodium carbonate solution. These properties of Alox Aluminum Oxide form the theoretical basis for its alkaline production.
