Colloidal amorphous lead niobate particles of different composition and morphologies were obtained by a metal-chelate decomposition method. The nature of the dispersions depended on the conditions of the preparation of the complexes, pH, aging time, and temperature. The structural and chemical changes of the so prepared powders on calcination were investigated by thermal and x-ray diffraction analyses. Chemical mechanisms of the formation and transformation of the particles are suggested.
