why can nano alumina be used as polishing powder
With its high hardness and good stability, nano alumina has outstanding performance in industrial applications such as precision machining and manufacturing
It is a widely used polishing abrasive at present
With the development of modern technology, it is more widely used in the production of resin polishing abrasive, especially for high-precision grinding and mirror polishing

Nano alumina is used as polishing powder mainly in the following aspects:
(1) The particle size of the powder is small, uniform and consistent, within the allowable range;
(2) It has high purity of 99
99% and does not contain mechanical impurities;
(3) It has good dispersibility and adsorption to ensure the uniformity of the processing process;
(4) The powder particles have a certain lattice shape and form sharp corners when broken, so as to improve the polishing efficiency;
(5) It has appropriate hardness and density, and has good wettability and suspension with water, because the polishing powder needs to be mixed with water

High hardness and low toughness materials have good grinding ratio and are suitable for polishing materials
Alumina belongs to corundum
Nano zirconia and nano diamond powder are good polishing materials
Nano diamond is generally used for mirror polishing and inner wall polishing of automobile internal combustion engine

It should also be noted that during grinding and polishing, whether it is alumina polishing solution, diamond polishing solution, or polishing paste and other polishing agents, spray or apply them to the center of the rotary table as much as possible to ensure that the polishing agent is lost as little as possible and effectively grind and polish the sample surface
