Whether the marble can be polished depends not only on the particle size of the polishing powder, but also on the morphology, hardness and other factors of the polishing powder. XR and BR alumina polishing powder is a spherical-like polishing powder with an average particle size of 0.3um, 0.5um, 1um and high crystallinity. It is used for polishing marble mirrors.
Alumina Polishing powder requires high hardness and particle size.
