Abstract
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.
