An excess of barium (Ba/Ti ratio >1) can control the graingrowth during sintering and the microstructure, thus tail the electric properties of barium titanate ceramics. It has long been believed that excess barium can only be dissolved in BaTiO 3 in very small amount, i.e.<100 ppm,, and this amount is recently extended up to 1%, .

Titanates are compounds containing titanium, oxygen, and at least one additional metallic element.Some of the most common titanates are strontium titanate, barium titanate, calcium titanate, and dysprosium titanate. Strontium titanate, at room temperature, is a centrosymmetric paraelectric material with a perovskite structure.However, at low temperatures it nears a ferroelectric phase ...
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.
