Experimental Study on Reutilization of Waste Rare Earth Polishing Powder AITranslate
Abstract AITranslate
Ultraprecise rare earth polishing powder was prepared by low temperature decomposition of waste rare earth polishing powder with commercially available inorganic acid. The effects were investigated of type and dosage of inorganic acids, reaction temperature and time, and leaching times on rare earth leac- hing. The particle size and chemical composition of the prepared rare earth polishing powder were deter- mined, and the reaction mechanism during the preparation process was analyzed. The results indicate that the rare earth leaching rate is up to 99.23 % after two-stage leaching of waste rare earth polishing powder with hydrochloric acid under the following conditions, hydrochloric acid concentration of 37% ,acid/mate- rial mass ratio of 3.5 ,reaction temperature 98-103 ℃,primary leaching for 8 h,and secondary leaching for 7 h. Ultraprecise rare earth polishing powder containing 67.64% CeO2,24.39% La2 03 and 6.00% F can be prepared,and its particle size distribution is uniform with average particle size of 0.39 μm.
