Abstract

In this article, nano-Bi₂O₃ powder was synthesized by the solution combustion synthesis method using bismuth nitrate as oxidant and citric acid as fuel. The investigation was focused on the effect of calcination temperature on the size of nano-Bi₂O₃, phase transformation, and morphology. The β-Bi₂O₃ powder was synthesized at 300°C for 2 h and characterized by SEM, TEM, XRD, and TG-DTA. Bi₂O₃ nanoparticles as small as 10.7 nm were formed using 0.005 mol citric acid as the fuels and 0.04 g PEG-20000 as the dispersant.
