PREPARATION AND PROPERTIES OF RARE EARTH HYDROXIDES AND OXIDES ULTRAFINE POWDERS IN ALCOHOL

摘要: A series of rare earth hydroxides and oxides ultrafine powders have been prepared by precipitation method using alcohol as dispersive and protective reagent.It was first to find that the crystallite size of cubic rare earth oxides had lanthanide shrinking effect,but average crystal lattice distortion rate possessed lanthanide swelling effect;the change of diffraction intensity with atoiaic number presented an inverted W type,and double peaks structure was formed.
