Aluminum hydroxide JJ for ceramics, flame retardants and catalysts

Aluminum hydroxide JJ for ceramics, flame retardants and catalysts
Aluminum hydroxide, with the chemical formula Al (OH) 3, is a hydroxide of aluminum
Aluminum hydroxide can react with acid to form salt and water, and can react with strong alkali to form salt and water
Therefore, it is also an amphoteric hydroxide
After heating and dehydration in the air, it can be transformed into alumina
Aluminum hydroxide is a widely used chemical product

Main purpose:
1
  Chemical raw materials
Because aluminum hydroxide can be produced on a large scale, with sufficient raw materials, high purity and easy dissolution in acid and alkali
Therefore, aluminum hydroxide is an important raw material for the preparation of aluminum salts, such as barium aluminate, aluminum sulfate and so on

2
Flame retardant
Aluminum hydroxide powder is usually regarded as an ideal flame retardant filler for plastics, unsaturated polyester, rubber and other organic polymers because of its filling, flame retardant and smoke elimination functions

2
  ceramics
Aluminum hydroxide is calcined at high temperature to obtain alumina, which has high thermochemical stability, thermal strength, creep resistance, dielectric properties and low coefficient of thermal expansion
It is an important material for the synthesis of ceramics
In the process of ceramic synthesis, aluminum hydroxide activates and controls the crystallization process, so as to control the phase formation of the composite

4
Sewage treatment
Aluminum hydroxide is mainly Al (OH) 4 - in water, which can precipitate the toxic heavy metals in sewage by coprecipitation, and then filter to achieve the effect of water purification
Aluminum hydroxide also has a high specific surface area, which can adsorb colloids, suspended solids, dyes and organic matter in sewage on the surface

5
Catalyst support
During the preparation of aluminum hydroxide, the target products with different specific surface area, pore volume, pore structure and crystal structure are prepared by controlling the temperature, concentration and pH of reactants
It can be effectively used as a catalyst carrier for the hydrogenation of unsaturated carbonyl compounds and the preparation of fullerenes
