摘要：

The objective of this communication is to study by means of electron microscopy the formation of reactive sodium niobate nanoparticles obtained by a novel polymeric precursor route using DL-malic acid as chelating agent. Conventional electron microscopy and electron-diffraction were used to investigate the crystallization, the particle size evolution and the formation of nanoparticle agglomerates.
