Abstract
The aim of this work was to investigate the influence of precipitation parameters on the morphology of obtained thulium oxide powders. Tm2O3 precursor powders were synthesized by precipitation method using 0.1–0.25M water solutions of thulium nitrate and 1.5M ammonium hydrogen carbonate water solution as a precipitation agent. The processes were conducted at different temperatures (25–50°C). The result showed that the morphology of the obtained thulium oxide (Tm2O3) powders depends both on the molar concentration of thulium nitrate and the temperature of precipitation. Small, round, loosely agglomerated Tm2O3 nanoparticles were obtained after air calcination of precursor precipitated at room temperature with the use of 0.1M thulium nitrate solution.
