The role of pickling of white corundum powder
The role of pickling with white corundum powder
1. Remove oxides and some impurities
When white corundum micropowder is mixed with acidic solutions such as dilute nitric acid or dilute sulfuric acid, the oxidizing and corrosive properties of the acid are used to chemically react with the oxides and impurities on the surface of the micropowder to separate them from the micropowder. Micronized powder.
2. Maintain and improve hardness
Pickling can remove soft impurities and oxides on the surface of the micro powder, making the hardness of the white fused aluminum oxide micro powder more uniform and stable.
3. Improve chemical stability
The pickled white fused alumina powder has excellent chemical stability,
can withstand the appearance of various chemical substances, and has good corrosion resistance.
4. Optimize particle size distribution
The pickling process is also beneficial to optimizing the particle size distribution of white fused alundum powder.and the more concentrated the particle size distribution, the better the use effect.
