Matrix isolation of ferroelectric BaTiO 3 nanoparticles was executed by formation of protective silica shell (via hydrolysis and polycondensation of tetraethyl orthosilicate) on particles of precursor—barium titanyl oxalate. Synthesized BaTiO 3 –SiO 2 composites have been characterized by IR spectroscopy, XRD, TEM, DTA/DTG methods.
