Good chemical stability: Stable at room temperature, but prone to decomposition in strong acid and strong alkali solutions. When heated,Aluminum hydroxide decomposes and dehydrates to form aluminum oxide.
Excellent flame retardancy: During pyrolysis, no toxic or corrosive gases are produced. Instead, Aluminum hydroxide absorbs heat and releases water vapor, endowing the product with flame retardant and self-extinguishing properties.
Surface modifiability: After advanced surface treatment processes, Aluminum hydroxide can have good compatibility with polymer materials. When added in large quantities, it can reduce the impact on the physical and mechanical properties of the materials.

High whiteness: Usually in the form of white powder, Aluminum hydroxide has a high whiteness. For instance, the whiteness of some products can reach over 97%, which can meet the requirements of application scenarios with high color demands on the products.
Controllable particle size: The particle size distribution is uniform, and there are multiple particle sizes to choose from 2.5 microns (5000 mesh), 3 microns (4000 mesh), 5 microns (2500 mesh), etc. Customization can be made according to different application requirements.
Application of Aluminium Hydroxide
Plastics, rubber and fiberglass reinforced plastics
As flame-retardant fillers, they can enhance the flame-retardant performance, leakage resistance, arc resistance and wear resistance of products.
01
Artificial marble slabs
Used for filling, they can improve the performance of the slabs, such as increasing hardness and gloss.
02
Electronics industry
Aluminum hydroxide is used for potting compounds, surface coatings of copper clad laminates, and flame-retardant paper, etc., which can enhance the insulation and flame-retardant performance of electronic components.
03
In the papermaking industry
Aluminum hydroxide it can be used as a colorant filler and surface coating to enhance the brightness of paper, improve printing characteristics and ink adsorption, and also reduce dust generation.
04
Other fields
Aluminum hydroxide can also be applied in daily cosmetics, medicine, glass industry, etc. For instance, in toothpaste, its mild frictional property can be utilized to clean and polish teeth.
05
Production Process of Aluminium Hydroxide
Digestion of bauxite ore: The bauxite ore is crushed and heated with sodium hydroxide at temperatures between 150 and 200 °c. The ‘digested’ bauxite ore is easier to process.
Filtration: In this process, the aluminum oxide from bauxite ore is converted to sodium aluminate. Filtration enables the separation of soluble sodium aluminate from insoluble impurities present in the bauxite ore. Rotary sand traps and flocculants such as starch are used to discard the solid impurities.
Seeding: In the final step of this process, the supersaturated solution of aluminium hydroxide and sodium aluminates is seeded with highly pure aluminium hydroxide crystals to facilitate the precipitation of al(oh)3 crystals. This is an economical process since the heated solution doesn’t need to be cooled further prior to extraction.
