Decomposition Study of Praseodymium Oxalate as a Precursor for Praseodymium Oxide in the Microwave Field.

ABSTRACT: Micron-sized praseodymium oxide powders are prepared successfully from the praseodymium oxalate in a microwave field at 750 °C for 2 h in the present study. X-ray diffraction (XRD) analysis demonstrates that the presence of cubic structured crystalline Pr₆O₁₁ and complete decomposition of the precursor are confirmed by Fourier transform infrared (FT-IR) analysis. The scanning electron microscopy (SEM) results show yield powders with the desired particle size and uniform morphologies. Particle size analysis demonstrates that the median diameter (D ₅₀) becomes stable at 750 °C. The D ₅₀, average surface area, pore diameter, and pore volume calculated by Brunauer -Emmett-Teller (BET) are 4.32 μm, 6.628 m²/g, 1.86 nm, and 0.0
