  2. Barium titanate - Wikipedia

    en.wikipedia.org/wiki/Barium_titanate

    Barium titanate (BTO) is an inorganic compound with chemical formula BaTiO 3. It is the barium salt of metatitanic acid. Barium titanate appears white as a powder and is transparent when prepared as large crystals. It is a ferroelectric, pyroelectric, and piezoelectric ceramic material that exhibits the photorefractive effect.

    The most commonly produced piezoelectric ceramics are lead zirconate titanate (PZT), barium titanate, and lead titanate. Gallium nitride and zinc oxide can also be regarded as a ceramic due to their relatively wide band gaps. Semiconducting PMs offer features such as compatibility with integrated circuits and semiconductor devices. Inorganic ...

    Barium, typically as barium nitrate imparts a yellow or "apple" green color to fireworks; [30] for brilliant green barium chloride is used. Barium peroxide is a catalyst in the aluminothermic reaction for welding rail tracks. It is also a green flare in tracer ammunition and a bleaching agent. [31] Barium titanate is a promising electroceramic ...

    The term titanates usually refers to titanium(IV) compounds, as represented by barium titanate (BaTiO 3). With a perovskite structure, this material exhibits piezoelectric properties and is used as a transducer in the interconversion of sound and electricity. [6] Many minerals are titanates, such as ilmenite (FeTiO 3).
