Product Description

Product Description

Ceramics Al2O3 Powder Aluminum Oxide Polishing Powder
Alumina Lapping Powder for Coating

Taking the superior industrial alumina as raw material, Calcined Alumina is produced through the method of advanced high temperature down draught kiln with scientific calcine. These make sure it has the advantages as follows: less trash, high transfer rate, stable contraction, and great variety of goods. The shape is fine sand or powdery with white color, As its equal particle sizes and dispersing easily, it has a good sinterability. Calcined Alumina is the basic raw material for heat-resistance and corrosion-resistance products, such as high-alumina refractory, high level ceramic products, car used sparking plug, electronic ceramic parts, material for iron and steel oven, high temperature friction material and polishing grinding products, ect.
Application:Widely used in refractory industry, ceramic industry, polishing industry , etc.


Advantages:
1. High hardness and mechanical strength;
2. Excellent thermal and electrical insulation characteristics;
3. Resists wear, chemically inert, stable at high temperatures.

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
