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
A certain amount nano-spherical alu powder can help to solve problems in ceramics. These ceramics can also be transformed into low-temperature plastic-spherical-alumina ceramics.
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 and other materials. This can significantly improve hardness and corrosion resistance as well as wear resistance and fire resistance.
4. Materials for optical purposes
The absorption of ultraviolet light is strong for nanosized, spherical-sized alumina powders. Its wavelength is below 250nm. The blue shift phenomenon of micro-ultraviolet absorbtion can be utilized to absorb the 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 is suitable for use in transparent ceramics, which are used to make high-pressure sodium lamps. It can also be combined with rare earth phosphors to create a luminescent lamp. The main fluorescent material used in future manufacturing of luminous lamps will also be made from this material.
5. Semiconductor material
This nano-sized spherical powder of alumina is very sensitive to humidity.
