Synthesis of lanthanum carbonate nanoparticles via sonochemical method for preparation of lanthanum hydroxide and lanthanum oxide nanoparticles

▶ Lanthanum carbonate nanoparticles were synthesized from the reaction of lanthanum acetate and Na2CO3 under sonication via sonochemical method. ▶ Lanthanum hydroxide nanoparticles were prepared from hydrolysis of resulted product at 110 °C for 24 h. ▶ La2O3 nanoparticles were obtained by calcinations of the nanoparticles of La2(CO3)3 at 600 °C.
