    OverviewProduction and handling propertiesStructureUsesNatural occurrenceSee alsoExternal links

    Barium titanate can be synthesized by the relatively simple sol–hydrothermal method. Barium titanate can also be manufactured by heating barium carbonate and titanium dioxide. The reaction proceeds via liquid phase sintering. Single crystals can be grown at around 1100 °C from molten potassium fluoride. Other materials are often added as dopants, e.g., Sr to giveform solid solutions with strontium titanate. It reacts with nitrogen trichloride and produces a greenish or gray mixture; the ferroelectricproperties of the mixtur
