Product Description

Product Description

1. Definition

Aluminum hydroxide, with the formula Al(OH)3, is an inorganic compound. It is a white, odorless solid formed by the combination of aluminum, oxygen, and hydrogen. As an amphoteric compound, it can react with both acids and bases, making it useful in various industrial applications.

2. Physical and Chemical Properties

Physical Properties: It appears as a fine, white powder with low density. Insoluble in water, it has a relatively high melting point when decomposed under heat.
Chemical Properties: Reacting with HCl, it forms aluminum chloride and water. With strong bases, it produces aluminates. Its amphoteric nature allows it to participate in diverse chemical reactions.

3. Production Methods

    From Bauxite: The most common method starts with bauxite ore. The ore is treated with NaOH to dissolve aluminum compounds, then precipitated as aluminum hydroxide by adjusting pH.

   Precipitation Reaction: Reacting aluminum salts, like aluminum sulfate, with NH3 - containing solutions also yields aluminum hydroxide through a precipitation process.

4. Storage Methods

Store aluminum hydroxide in a dry, cool place, away from direct sunlight. Use sealed containers to prevent moisture absorption and contamination. Avoid storing it near acids or strong bases to prevent unwanted reactions.

5. Market Information

The market demand for aluminum hydroxide is driven by industries such as plastics, ceramics, and water treatment. Its price is influenced by raw material costs, production scale, and changes in demand. Growth in flame - retardant applications also impacts its market trend.

6. Downstream Industrial Chain

     Plastics Industry: Used as a flame retardant to enhance fire resistance of plastics.

     Ceramics Industry: Helps improve the texture and strength of ceramic products.

     Water Treatment: Functions as a coagulant to remove impurities from water, purifying it for various uses.

Application

Flame - Retardant Additive
Aluminum hydroxide serves as an effective flame - retardant in various industries. When added to plastics, rubber, and textile materials, it decomposes upon exposure to high heat, releasing water vapor. This dilutes flammable gases and cools the material, inhibiting fire spread. For example, in the production of cables used in buildings, its inclusion enhances fire safety, reducing the risk of large - scale conflagrations.

Water Treatment Agent
In water treatment processes, aluminum hydroxide plays a crucial role. As a coagulant, it helps remove suspended particles, colloids, and impurities from water. When added to raw water, it forms large flocs that attract and trap contaminants, making them easier to filter out. This purification method is widely used in municipal water treatment plants to ensure clean, potable water for communities.

Catalyst Support
In the chemical industry, it functions as a support for catalysts. Its high surface area and porous structure provide an ideal base for active catalyst components, increasing their efficiency. For instance, in petroleum refining processes, catalysts supported by aluminum hydroxide help break down complex hydrocarbons into simpler, more useful products, facilitating the production of gaso-line, die-sel, and other fuels.

Ceramics and Refractory Materials
Aluminum hydroxide is a key ingredient in ceramics and refractory materials. In ceramics, it contributes to the formation of a smooth, durable glaze and improves the mechanical properties of ceramic products. For refractory materials, it enhances heat resistance, allowing them to withstand extremely high temperatures in industrial furnaces, kilns, and other high - heat environments.

Paper Industry Additive
In the paper - making process, aluminum hydroxide is added to improve paper quality. It acts as a filler, enhancing the opacity, brightness, and smoothness of paper. Additionally, it helps control the pH level during paper production, protecting equipment from corrosion and ensuring consistent paper properties.
