Alumina Trihydrate

Alumina trihydrate is a white crystalline powder with a specific gravity of 2.42 and a melting point of 300°C (loss of water). It is insoluble in water and alcohol, but soluble in inorganic acids and sodium hydroxide solutions. Aluminum hydroxide gel is a white, viscous suspended colloid that can release a small amount of water after standing.it is widely distributed in nature and can be extracted from various boulders and rocks.

1. Stability: it has high chemical and thermal stability, which allows it to maintain its performance unchanged in high temperatures or chemically active environments. This stability makes it ideal in applications that require prolonged exposure to harsh conditions, such as high-temperature processing or chemical reactions.

2. Adsorption: it has high specific surface area and adsorption performance. This enables it to effectively adsorb and remove various impurities and pollutants, so it is widely used in industry as catalysts, fillers, and adsorbents. For example, it can be used as an adsorbent in water treatment to remove heavy metal ions and other harmful substances in water.

3. Flame retardant properties: it also has good flame retardant properties. Due to its endothermic dehydration characteristics during thermal decomposition, it can be used as a flame retardant for plastics and rubber to improve the flame retardant properties of the material. This characteristic makes it an important application in the field of fire safety.

1.Industrial application:

Catalyst: it can be used as a catalyst to speed up the rate of certain chemical reactions.

Filler: It can be used as filler in plastics, rubber, textiles and other materials to increase the strength and hardness of these materials.

Preparation of other alumina materials: It is also a precursor for the preparation of other alumina materials, such as high-purity α-Al2O3 or γ-Al2O3.

2. Electronic parts manufacturing: In the production of certain electronic parts, it can be used as a fire-resistant insulating material to protect circuits and components from high temperature and electromagnetic interference.

3. Adsorption and purification: it is used as an adsorbent and has important applications in the fields of water treatment and waste gas treatment. It can effectively remove impurities in water and harmful substances in waste gas.

4. Pharmaceutical field:

Antacids: Aluminum oxide trihydrate neutralizes stomach acid and is used to relieve symptoms such as stomach pain and indigestion.

5. Cosmetics field:

Sunscreen: Aluminum oxide trihydrate absorbs UV rays and acts as a sunscreen to protect the skin from UV rays.

6. Construction field: In the field of architecture and construction, it also plays an important role.
