Barium titanate Chemical Properties,Uses,Production

Description

Attributing to its ferroelectricity, barium titanate is applied as a semiconductor with positive temperature coefficient of resistivity. It is one of the most important electroceramic materials among all the ferroelectric materials. Barium titanate has also dielectric properties, which can be used in the manufacture of ceramic capacitors. Furthermore, barium titanate has piezoelectric property and can be used in electrical devices such as actuators, accelerators, ultrasonic generators, piezoelectric transducers, filters, and sensors.

Chemical Properties

White crystalline solid; exists in five crystal modifications; the common tetragonal form has a Curie point of 120°C; exhibits ferroelectric and piezoelectric properties; density 6.02 g/cm3; melts at 1,625°C; insoluble in water and alkalies; slightly soluble in dilute mineral acids; dissolves in concentrated sulfuric acid and hydrofluoric acid.

Uses

Barium titanate has many important commercial applications. It has both ferroelectric and piezoelectric properties. Also, it has a very high dielectric constant (about 1,000 times that of water). The compound has five crystalline modifications, each of which is stable over a particular temperature range. Ceramic bodies of barium titanate find wide applications in dielectric amplifiers, magnetic amplifiers, and capacitors. These storage devices are used in digital calculators, radio and television sets, ultrasonic apparatus, crystal microphone and telephone, sonar equipment, and many other electronic devices.

Uses

In electronic devices, e.g., as voltage-sensitive dielectric in so-called dielectric amplifiers, in computer elements, magnetic amplifiers, memory devices.

Uses

Barium titanate (BaTiO3, BT) is one of the widely used materials in electronic ceramics. Because of its very high permittivity, it could be used in capacitors with outstanding properties by doping. Because barium titanate is used in large quantities as a material in electronic devices, considerable energy savings could be achieved if barium titanate could be sintered at a reduced temperature. It is reported that for LTCC (Low Temperature Cc-fired Ceramics) application, barium titanate is sintering at 1000℃ for 24 hours with the incorporation of silicate glass system. In addition, there is a report saying that a sintered body of relative density around 90% was achieved by 900℃ for 8 hours by adding boron oxide or lead borate to a barium titanate.

Preparation

Barium titanate is made by sintering a finely powdered mixture of barium carbonate and titanium dioxide in a furnace at 1,350°C. The calcined mass is finely ground and mixed with a binder (plastic). The mixture is subjected to extrusion, pressing or film casting to obtain ceramic bodies of desired shapes. Plastic is burnt off by heating and the shaped body is sintered by firing and then polished.
Barium titanate also may be prepared by other methods. These include ignition of barium and titanium alcoholates in an organic solvent; treatment of tetraethyl titanate or other alkyl ester of titanium with an aqueous solution of barium hydroxide; and ignition of barium titanyloxalate.
