MANUFACTURING METHOD OF PEROVSKITE POWDER, PEROVSKITE POWDER MANUFACTURED BY USING THE METHOD, AND A LAMINATED CERAMIC ELECTRONIC COMPONENT MANUFACTURED WITH THE METHOD CAPABLE OF LOWERING PORE GENERATION RATE OF THE PEROVSKITE POWDER
MANUFACTURING METHOD OF PEROVSKITE POWDER, PEROVSKITE POWDER MANUFACTURED BY USING THE METHOD, AND A LAMINATED CERAMIC ELECTRONIC COMPONENT MANUFACTURED WITH THE METHOD CAPABLE OF LOWERING PORE GENERATION RATE OF THE PEROVSKITE POWDER
PURPOSE: A manufacturing method of perovskite powder, perovskite powder manufactured by using the method, and a laminated ceramic electronic component manufactured with the method are provided to enhance dispersibility by using metallic oxide sol with high concentration and high purity.;CONSTITUTION: A manufacturing method of perovskite powder comprises the following steps: removing impurities by washing water containing metal oxide(s1); adding deionized water and acid or base to the water containing metal oxide and obtain a metal oxide sol at 0-60 deg. Celsius for 0.1-72 hours(s2); mixing the metal oxide sol with a metal salt in order to form perovskite particle-core at 60-150 deg. Celsius(s3); and obtaining the perovskite powder by growing the perovskite particle nuclear through a hydro-thermal treatment(s4,s5). 0.0001-0.2 mole of acid or base is added to the water containing metal oxide.;COPYRIGHT KIPO 2012
