Barium titanate is a kind of strong dielectric compound, which is a widely applied electronic ceramic materials. It has high dielectric constant and low dielectric loss. Barium titanate whisker is an important ferroelectric, which own ferroelctric property when temperature under 120℃. There are two different production methods, oxalate precipitation method and solid phase method. It is insoluble in water, hot dilute nitric acid and alkali, however soluble in concentrated sulfuric acid, hydrochloric acid and hydrofluoric acid.
