MECHANOCHEMICAL SYNTHESIS OF CEO2 NANOPOWDER USING PLANETARY BALL MILLING

open access: yesJurnal Sains dan Teknologi Reaksi, 2016
Nanocrystalline cerium dioxide (CeO2) had been successfully synthesized by mechanochemical technique at  12, 24, 36, 48 and 60 hours milling times. The starting materials, hydrated cerium carbonate and sodium hydroxide, were mixed in weight ratio of 4:1 and were milled in a planetary ball mill with ball to powder ratio of 10:1.
