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 metallurgy as well as electronics, national defense and aerospace, nuclear industry, and other areas. High-tech field.
Application of spherical allumina
1. Ceramic additives
The shortcomings of ceramics caused by low-temperature fragility and limited application range can be solved by adding a small amount of nanospherical Alumina powder. These ceramics can then be converted into low-temperature plastics spherical Alumina 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 make artificial tooth and bone.
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. Optical 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, 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 to make transparent ceramics for high-pressure sodium lamps. Rare-earth and rare-earth pigments can be combined to create the luminescent material in the luminous lamp. It will reduce cost and increase the life expectancy of the luminous lamp.
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 used extensively as a substrate for large-scale integrated Circuits.
