Abstract
PURPOSE: To obtain fine rare earth elements carbonate powder by mixing an aq. soln. of a rare earth elements salt with an aq. soln. contg. certain times as much carbonate ions as the rare earth elements by mol after which the pH value of the resulting rare earth elements carbonate slurry is adjusted to a prescribed range.
