Nanosized lead zirconate (PbZrO 3 ) powder was synthesized from its oxalate precursor, namely lead zirconyl oxalate (LZO). LZO heated in a microwave heating system for 1 h yielded the PbZrO 3 at 600°C. The same precursor (LZO), when heated in a resistance‐heated furnace at 850°C for 3 h, does not give a pure product. Thermogravimetry, differential thermal analysis, and X‐ray diffraction techniques were used to characterize the precursor and optimize the conditions for microwave processing. The particle size of PbZrO 3 powder prepared at 600°C using microwave heating was measured using transmission electron microscopy (TEM). The TEM images show that the particles of PbZrO 3 are spherical in shape and that the particle size varies between 20 and 22 nm.
