The properties of spherical-alumina
Ultra-fine, spherical, alumina has many excellent properties, including high resistance to corrosion, high temperatures resistance, high hardness and strength, wear resistance as well as oxidation resistance. It is widely used in the chemical industry, electronics and national defense. High-tech field.
Application of spherical allumina
1. Ceramic additives
A certain amount of nanospherical, alumina powder can effectively address the weaknesses of ceramics due low-temperature fracture and limited application range. These ceramics can then be converted into low-temperature plastics spherical ceramics.
2. Composite materials
Nano-spherical powdered alumina can be used to create new composite ceramic materials with unique properties. It can also be used to create artificial teeth or bones.
3. Coatings to protect the surface
Spherical alumina powder particles can be sprayed on metals, polymers, etc. to improve hardness, corrosion resistance wear resistance and fire resistance. They can also be used as surface protection for machinery, knives, chemical pipelines, and other equipment.
4. Optical materials
The absorption of ultraviolet light is strong for nano-sized spherical powdered alumina. It is below 250nm. The blue shift phenomenon of nanoultraviolet absorbtion can be used to absorb the spherical, alumina powder. It does not emit harmful ultraviolet light and will not affect the phosphor’s luminescence. The nano-spherical form of alumina can also be used in high-pressure sodium lamps to create transparent ceramics. Rare-earth phosphors can also be used as the luminescent material in the luminous lamp. It will not only lower the cost, but also prolong the life of the luminous bulb.
5. Semiconductor materials
Nano-scale spherical Alumina Powder is very sensitive to humidity. It has an extremely high value in temperature sensors and can be widely used for substrate materials for large-scale integrated Circuits.
