The aim of this work was to investigate the influence of precipitation parameters on the morphology of obtained thulium oxide powders. Tm 2 O 3 precursor powders were synthesized by precipitation method using 0.1–0.25 M water solutions of thulium nitrate and 1.5 M 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 (Tm 2 O 3 ) powders depends both on the molar concentration of thulium nitrate and the temperature of precipitation. Small, round, loosely agglomerated Tm 2 O 3 nanoparticles were obtained after air calcination of precursor precipitated at room temperature with the use of 0.1 M thulium nitrate solution.
