barium calcium titanate powder method , calcium , barium titanate powder, multilayer ceramic capacitors

摘要

The invention BaTiO ₃ and calcium salts on the surface of the nano-sized powders precipitation heat treatment and this by BaCaTiO ₃ of synthesizing a barium calcium titanate powder (BaCaTiO ₃ ) relates to the powder production process. Production method of the barium calcium titanate powder of the present invention , BaTiO ₃ and Ca salts comprising the steps of: providing a powder mixed aqueous solution , ; in the mixed aqueous solution of BaTiO ₃ step to precipitate the calcium salt on the surface of the powder , ; calcining the dried powder obtained from the mixed solution to obtain synthesized by BaCaTiO ₃ powder, comprising the step of grinding you made. In the present invention , the barium calcium titanate powder and a multilayer ceramic capacitor using this powder is also provided .
