Barium titanate (BaTiO3) is one of the most important ceramic materials used in electronics. As an intrinsic ferroelectric material it can be utilized for various applications like multilayer capacitors, grain boundary capacitors, low-temperature sensors and thermistors. There is a growing need for efficient methods of producing barium titanate layers, particularly if they are thin and crack-free. This method allows for the preparation of thin, whole layers even in complex shapes without the use of extremely toxic solutions currently in use in other methods.
