In the present study, we presented a review progress in sol-gel method for the synthesis of powders of ferroelectric ceramics of the PbTiO3–PbZrO3 system, based on the controlled hydrolysis of mixtures of salts or organometallic compounds of lead, zirconium, and titanium. To obtaining materials of the PbTiO3–PbZrO3 system, the main attention is paid to the sol-gel conditions, the heat treatment conditions, the raw materials, the obtaining the precursor conditions, the gels drying, and the PbTiO3–PbZrO3 powder crystallization.
