Preparation of Ultra-fine CeO_2 Precursor for Optical Glass Polishing Material AITranslate
Abstract AITranslate
The ultra-fine CeO2 precursor for optical glass polishing material was prepared by selective oxidation and precipitation, washing, drying and calcination from low-cerium complex rare earth chlorides solution with NH3.H2O as precipitator, air and H2O2 as oxidative agent.The effect of reaction conditions and feeding mode on the content of CeO2 in precursor,and the correlativity between calcination temperature and particle size,specific surface area and mineralogical composition of precursor powder were investigated.The results show that by forward dripping, pH value controlled within 4.5 and 5.5,Ce3+ can be oxidized into Ce4+ to form hydroxide precipitant,followed by separation with other RE ions the ultra-fine polishing powder and precipitation before calcinations at 600～700 ℃ to obtain ultra-fine CeO2 precursor with CeO2 content over 80%,median particle size D50 less than 1.5 μm.
