Preparation of Lanthanum Oxide Nanoparticles by Chemical Precipitation Method

Abstract:

This paper investigated synthesis of Lanthanum oxide nanoparticles by precipitation method. Effects of reactant concentration, precipitator and dispersant agent on properties of Lanthanum oxide particles were studied. Lanthanum oxide particles were characterized by XRD and SEM. Experimental results showed that ammonium bicarbonate and PEG20000 were appropriate precipitation and dispersant respectively. The optimum process conditions were as follows: concentration of Lanthanum nitrate was 0.18mol/L, concentration ammonium bicarbonate of was 0.6mol/L, reaction temperature was 30. The average particles size of Lanthanum oxide powders with spherical shape gained was about 188 nm.
