Best quality Polishing Alumina Powder - 4N 99.99% high purity alumina ball – Zhanchi
Best quality Polishing Alumina Powder - 4N 99.99% high purity alumina ball – Zhanchi Detail:
Alumina ball, also known as modern water purification activated bauxite, is a porous, highly dispersed solid material and has the characteristics required by the catalyst. Therefore, it is usually used as a catalyst in the chemical industry. According to the physical properties of alumina, alumina can be divided into three types: sand, flour and intermediate. These three types of alumina have great differences in physical properties. Sandy alumina has smaller bulk density, larger specific surface area, slightly smaller repose angle, contains a small amount of a-Al2O3, has more and uniform coarse particles and high strength. Flour alumina has large bulk density, small specific surface area, more a-Al2O3, more fine particles and poor strength. The physical properties of intermediate alumina are between the two.
Our 4N 99.99% high purity alumina ball has the characteristics of high purity, high hardness, high density, low wear, smooth surface and corrosion resistance. It is the most ideal grinding medium for grinding glaze, blank and various powder materials.
