Patent number: 9242922Abstract: A method for producing a high-quality barium titanyl salt includes using, as the fluids to be treated, at least two kinds of fluids, namely, a barium titanium mixed solution that is obtained by dissolving both a barium compound and a titanium compound in a solvent, a compound solution that is obtained by dissolving, in a solvent, a compound capable of deposing the barium and titanium contained in the barium-titanium mixed solution into a barium titanyl salt, and if necessary, one or more other fluids; and mixing these fluids together in a thin film fluid formed at least between two treating surfaces and to form a barium titanyl salt. The treating surfaces are so arranged as to face each other in an approachable/separable state with one of the treating surfaces and being capable of turning relatively to the other.Type: GrantFiled: March 27, 2012Date of Patent: January 26, 2016Assignee: M. TECHNIQUE CO., LTD.Inventor: Masakazu Enomura

Patent number: 9061945Abstract: There are provided a method of manufacturing perovskite powder, and perovskite powder and a multilayer ceramic electronic component manufactured thereof. The manufacturing method includes: washing metal oxide hydrate to remove impurities therefrom; adding pure water and an acid or a base to the metal oxide hydrate to prepare a metal oxide sol; mixing the metal oxide sol with a metal salt to form perovskite particle nuclei; and conducting grain growth of the perovskite particle nuclei by hydrothermal treatment to produce perovskite powder. The method of manufacturing perovskite powder and the perovskite powder manufactured by the same have advantages such as excellent crystallinity, reduced generation of fine powder, and favorable dispersion properties.Type: GrantFiled: September 6, 2013Date of Patent: June 23, 2015Assignee: SAMSUNG ELECTRO-MECHANICS CO., LTD.Inventors: Kum Jin Park, Sang Hyuk Kim, Hye Young Baeg, Hyung Joon Jeon, Sang Hoon Kwon, Chang Hak Choi
