Latest Patents

Takahasi holds a patent for a process for producing perovskite-type oxides of the ABO.sub.3 type. This process involves bringing a solution of element A (such as Pb, Ca, Sr, and/or La) and element B (like Ti and/or Zr) into contact with oxalic acid in the presence of an alcohol to precipitate oxalic acid salts. The acid radicals in the solution are then neutralized with an amine or ammonia. The resulting precipitate undergoes calcination, leading to the production of a fine-grained ferroelectric oxide with a sharp grain size distribution. This oxide's chemical composition can be precisely controlled, making it suitable for various advanced applications.
