Molecular formula : BaTiO3 CAS :
nature : also known as the Partial barium titanate (Jaime metatitanate). White powder. Quartet crystal and a variety of crystalline hexagonal type. The most common crystal Quartet. Crystal density 6.017g/cm3 Quartet. 1625 ° C melting point. The six-party 5.806g/cm3 crystal density. Soluble concentrated sulfuric acid, hydrochloric acid, hydrofluoric acid. Do not dissolve in water, heat of dilute nitric acid and alkaline solution. In less than 120 ° C with an iron -- nature, a high dielectric constant, toxic! By refining titanium tetrachloride solution and refined mixture of barium chloride solution, oxalic acid in refined by adding 70 ~ 100 ° C for the reactions to produce titanium oxygen barium oxalate precipitation, filtration, washing, drying, at 700 ~ 1000 ° Ccalcined obtained. Barium carbonate can also be used for titanium dioxide mixed with the grinding, extruding, in 1200 ° Cobtained. In the electronics industry for the manufacture of non-linear element, dielectric amplifiers, micro-capacitors, computer memory components, such as ultrasonic generator.
