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 metallurgy as well as electronics, national defense and aerospace, nuclear industry, and other areas. High-tech field.
Application of spherical allumina
1. Ceramic additives
A certain amount of nanospherical, alumina powder can be added to ceramics to solve their shortcomings due to low-temperature fracture and limited application range. The body can also be used to increase the ceramics’ toughness and lower the sintering temperatures.
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 and plastics. This can improve the hardness, corrosion resistance and wear resistance of the surface.
4. Optic materials
The absorption of ultraviolet light is strong for nano-sized spherical powders made from alumina spheres. It is less than 250nm in size. The blue shift phenomenon of nanoultraviolet absorbtion can be used to absorb the spherical, spherical Alumina powder. It does not emit harmful ultraviolet light and does 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 combined with it to create luminous lamps. It will not only lower the cost, but also prolong the life of the luminous bulb.
5. Semiconductor materials
The nano-scale, spherical alumina dust 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.
