The optimal chemical compositions have been chosen for the development of heating elements based on ferroelectricsemiconducting ceramics. The processes, which take place during the synthesis of the PTCR yttrium-doped barium titanate ceramics, have been analysed. The factors affecting ceramics electrophysical properties have been studied. In V.I. Vernadskii Institute of General and Inorganic Chemistry of NAS of Ukraine various doped by barium titanate thermos-stabilized ceramic heating elements with working temperature automatic control have been developed. These heating elements have been used by State Enterprise "Kharkiv design office for engine building" as a basis of oil heating devices which have been developed for the utilization in oil tanks of "ЕА-10М" power units. This allowed a significant (by 10-20oС) reduction of the starting temperature of a diesel engine in a cold season.
