The properties of spherical allumina
This ultra-fine, spherical, nonstick alumina offers excellent properties such as high resistance to corrosion, high resistance to heat, high hardness and high strength. It’s widely used in electronics, metallurgy as well national defense and aerospace industries. High-tech field.
Use of spherical aluminum
1. Ceramic additives
It is possible to solve ceramics’ shortcomings due to their low temperature brittleness, narrow application range and poor durability. By adding 5.0% of nano-spherical Alumina powder to traditional ceramics, the body will increase ceramic’s toughness and lower the sintering temperatures.
2. Composite materials
Alumina powder nano-spherical can be used to produce new types of composite ceramic materials, as well as artificial teeth or bones.
3. Coatings to protect the surfaces
The powdered spheres of alumina can be sprayed onto metals, plastics, or other materials to improve hardness, corrosion resistance and wear resistance. They can also serve as surface protection for machinery, knives, and chemical pipelines.
4. Materials for optical purposes
The absorption of ultraviolet light is strong for nanosized, spherical-sized alumina powder. Its wavelength is below 250nm. The blue shift phenomenon of micro-ultraviolet absorbtion can be utilized to absorb the spherical, spherical Alumina powder. The phosphor will still be luminously efficient despite the fact that it emits harmful ultraviolet light. 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 then be added as the luminescent materials of the luminous lamps. The main fluorescent material used in the production of future luminous lamps will also be made from this material.
5. Semiconductor material
This nano-scale powdered spherical aluminum powder is very sensitive to humidity.
