Precision polishing powders based on cerium dioxide contain a specially formulated mixture of rare earth metal oxides with a high degree of chemical cleaning, without phosphates and sulphides.
The controlled mixing of polishing powder during the production process allows changes in composition and in the abrasive ability ensuring selection of the polishing materials with different abrasion resistance.
The average grain size of the powder, size D50%, varies depending on the thermal calcination of hardening during the manufacturing process, it is important to choose the right type of polishing powder for certain types of glass or other machined material.

The polishing powder is used in the aqueous finely dispersed suspension.
