Products Description
Calcined alumina powder
Calcined alumina is produced by high quality and high purity raw material in the rotary furnace at reasonable temperature. It has characteristic of high conversion rate, stable crystallization and low impurity content, excellent performance of high mechanical strength, stable shrinkage rate, good electrical insulation, high wear resistance and outstanding corrosion resistance.
High temperature calcined alpha alumina powder is produced by aluminum hydroxide powder or industrial alumina powder as raw material, with 1450 ºC high temperature tunnel kiln calcining process, adding special additives reduce the impurity content, improve the alpha conversion rate, control the crystal shape, particle calcined under enough heat preservation time, and the micro powder is the use of high alumina ball mill grinding classification.
Alumina Powder Characteristics:
Al2O3 ≥(%) | 99..9 | α- Αl2O3 ≥(%) | 94 | |
SiO2 ≤(%) | 0.03 | L.O. I ≤(%) | 0.10 | |
Fe2O3 ≤(%) | 0.02 | True Density (g/cm3) | 3.94 | |
Na2O ≤(%) | 0.2 | Particle Size (D50μm) | 83-98 |
Alumina Powder Application advantage
1. When used in inks, painting and coating, it has significant photocatalytic antibacterial function, and has a good photo catalytic degradation of formaldehyde, benzene, ammonia and other harmful gases, it can well improve the adhesion , anti-aging performance;
2. Based on its strong capability of shielding ultraviolet and high transparency, it is widely used in cosmetics, paints and other products;
3. The product has the property of antibacterial, anti-aging and protection from UVR (ultraviolet radiation), and greatly improve adhesion strength of products.
4. The product has uniform particle size, big surface area, good dispersion and transparency, and has good property of anti-UV.
5. It has good compatibility with paint and coatings
6.The product can be made of liquid by adding water, then apply the liquid on the surface of ceramic brick, you can get 1cm nanometer titanium film with the property of killing bacteria after heating in a high temperature. The film can completely kill bacteria on the surface in the light or even the weak light.
7. The product can make sterilization 99%, and the degradative rate of formaldehyde reach to 85% in the sunlight and 4W UV light.
