Solid-phase method and liquid-phase method: These are methods to produce fine ceramics including barium titanate
. Under solid-phase method, raw materials are mixed up, react with each other when calcined at a high temperature, and come into compounds.

is traditionally prepared by the solid-state mixing of BaC[O.sub.3] and Ti[O.sub.2].

Among specific topics are the microstructure control of porous barium titanate
ceramics and their sensor properties, preparing bismuth-based perovskite oxides and their electric properties, preparing and characterizing mesoporous silica and lithium-ion-conductive halocomplex salt composite, and fabricating nanostructured zinc oxide films on plastic substrates by the pyrolysis method and applying them to dye-sensitized solar cells.
Since the discovery of various piezoelectric materials, barium titanate
(BaTiO3) has emerged as the most versatile material simultaneously functional for all types of piezoelectric devices.
Then barium titanate
, BaTi[O.sub.3], the first perovskite ferroelectric was discovered in 1942 and 1944 in the United States, Russia and Japan.
Although barium titanate
was the first piezoelectric material discovered, the ceramic lead zirconate titanate also known as PZT is the most commonly used material for piezoelectricity.
Other types of capacitor, such as barium titanate
, can lose up to 85% of capacitance at working voltage.
