  • Method for producing barium titanate-based powder, and multilayer ceramic capacitor
    Patent number: 10315928
    Abstract: A method for producing a barium titanate-based powder that includes mixing a titanium compound and a barium compound together with water and chlorine to prepare a slurry, and temporarily firing the mixture of the titanium compound and the barium compound which is contained in the slurry to provide a barium titanate-based powder. The chlorine in the slurry is in the form of chlorine ions in a ratio of 230 to 1100 wt ppm based on the amount of the barium titanate-based powder to be synthesized.
    Type: Grant
    Filed: November 6, 2015
    Date of Patent: June 11, 2019
    Assignee: MURATA MANUFACTURING CO., LTD.
