2. Barium titanate - Wikipedia

   en.wikipedia.org/wiki/Barium_titanate

   Barium titanate (BTO) is an inorganic compound with chemical formula BaTiO 3. 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. It is used in capacitors, electromechanical transducers and ...

3. Titanium compounds - Wikipedia

   en.wikipedia.org/wiki/Titanium_compounds

   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).

4. Titanate - Wikipedia

   en.wikipedia.org/wiki/Titanate

   Titanate. In chemistry, titanate usually refers to inorganic compounds composed of titanium oxides, or oxides containing the titanium element. Together with niobate, titanate salts form the Perovskite group. In some cases, the term is used more generally for any titanium-containing anion, e.g. [TiCl 6] 2− and [Ti (CO) 6] 2−.

   Barium, typically as barium nitrate imparts a yellow or "apple" green color to fireworks; [29] 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. [30] Barium titanate is a promising electroceramic ...

   2] 2+ ion, occurring every n ABO 3 layers, leading to an overall chemical formula of [Bi 2 O 2]-A (n−1) B 2 O 7. Their oxide ion-conducting properties were first discovered in the 1970s by Takahashi et al., and they have been used for this purpose ever since. [10] Dion−Jacobson phase: the intruding layer is composed of an alkali metal (M ...

8. Ferroelectricity - Wikipedia

   en.wikipedia.org/wiki/Ferroelectricity

   In lead titanate, another key ferroelectric material, although the structure is rather similar to barium titanate the driving force for ferroelectricity is more complex with interactions between the lead and oxygen ions also playing an important role. In an order-disorder ferroelectric, there is a dipole moment in each unit cell, but at high ...

   Barium titanate (BaTiO 3) – Barium titanate was the first piezoelectric ceramic discovered. Bismuth titanate (Bi 4 Ti 3 O 12) Sodium bismuth titanate (NaBi(TiO 3) 2) The fabrication of lead-free piezoceramics pose multiple challenges, from an environmental standpoint and their ability to replicate the properties of their lead-based counterparts.
