METHOD FOR MANUFACTURING BARIUM TITANYL OXALATE AND A METHOD FOR MANUFACTURING BARIUM TITANATE INCLUDING THE SAME CAPABLE OF OBTAINING BARIUM TITANATE POWDER WITH SMALL PARTICLE SIZES

摘要

PURPOSE: A method for manufacturing barium titanyl oxalate and a method for manufacturing barium titanate including the same are provided to uniform particle size distribution of the barium titanyl oxalate by lowering the permittivity of reactive medium before a synthesizing process with respect to the permittivity of water. ;CONSTITUTION: A method for manufacturing barium titanyl oxalate includes the following: A barium chloride solution, a titanium tetrachloride solution, and oxalic acid solution are prepared. The three solutions are mixed to synthesize barium titanyl oxalate at temperature between 5 and 40 degrees Celsius. The permittivity of at least one solvent for manufacturing the three solutions is controlled to be lower than that of water.;COPYRIGHT KIPO 2011
