Product Description

Product Description

Alpha Aluminum Oxide Alumina Powder for Polishing

Alumina powder, also known as aluminium oxide or activated alumina, is a chemical compound that is mainly used to produce aluminium.
Alumina powder is the ideal for aluminium production and others that require hardness and resistance to abrasion or other forms of chemical wear. Alumina powder is also ideal for products that require corrosion and wear resistance, and for products that require
high thermal conductivity, such electrically and thermally insulating applications.

Applications

1. Make transparent ceramics: high-pressure sodium lamps, EP-ROM window.
Αlpha-Al2O3 can be sintered into a transparent ceramic to use as a high-pressure sodium lamp material; as well as can be used as a compact fluorescent lamp in the protective layer of the phosphor layer to improve lamp life.

2. As high class polishing materials for: glass, metal, semiconductor materials, plastic, tape, grinding belt, etc.

3. As additive: reinforce paint, rubber, plastic wear-resistant.
As a new composite material, Al2o3 powder can be used as dispersion strengthening and additives, such as adding alumina nanoparticles into rubber, wear resistance can be improved several times.

4. Use as catalyst, catalyst carrier, analytical reagent.
By virtue of its special properties, Al2o3 powder is widely used as catalyst and its carrier, in ceramics and other fields.

5. Use for coating
Alumina nanoparticles as an optical material and surface protective layer of material can absorb ultraviolet light, and in some wavelengths of light excitation can be generated with the particle size of the wavelength of light.

6.Use for High strength ceramic
In ceramic applications, precision ceramics made by nano alumina powder have the similar metal plasticity and toughness, light weight, in particular, greatly enhance the strength.

By adding a small amount of nano-alumina in the conventional ceramic matrix can make the mechanical properties of materials doubled improve the toughness of ceramics to reduce its sintering temperature.

7. Use as cosmetic filler.

8.Use as material for Ceramic Composite Diaphragm
