Abstract

Abstract:

In order to study the influence of the preparation process on the polishing performance of rare earth polishing powder，cerium chloride was used as the cerium source and ammonium bicarbonate was used as the precipitant to prepare the precursor of rare earth polishing powder by the parallel addition method.This precursor could get the final polishing powder product after high temperature roasting treatment.During the study，the preparation parameters were carefully explored，including the concentration of rare earth solution，adding rate，stirring rate，precipitation temperature，the amount of polyethylene glycol dispersant（PEG-1000） used，aging temperature and aging time.After systematic experiments and analyses，the optimal preparation conditions were determined：the concentration of the rare earth chloride solution was 225 g/L，the drop acceleration rate was 2.5 mL/min，the stirring rate was 500 r/min，the precipitation temperature was 45 ℃，the amount of dispersing agent was 2%，the aging temperature was 45 ℃，and the aging time was 4 h.Under the optimal conditions，the particle size D₅₀ of the precursor was 1.229 μm，and the particle size D₅₀ of the final polishing powder was 1.087 μm.In addition，the homogeneity R of the polishing powder reached 1.85，and the polishing etching amount reached 0.473 2 mg/（cm²·min）.Compared with the traditional method of producing polishing powder，the present method eliminated the process of ball milling or air flow pulverization，and directly obtained the rare earth polishing powder that met the customer's demand.The preparation process of this research not only improved the production efficiency，but also optimized the quality and performance of the product，which was of great practical significance and application value for industrial applications.
