Ceramic powder and a multilayer ceramic capacitor

The present invention provides a ceramic powder and a multilayer ceramic capacitor. Appropriate firing temperature of the ceramic powder is provided a wide range, excellent productivity, especially useful for forming a thin layer of 1μm or less of the dielectric layer, and barium titanate having a perovskite structure as the main component, it is possible to provide high yield MLCC article. The ceramic powder is 200nm or less comprising barium titanate ceramic powder having a perovskite structure was observed by an average particle diameter measured by SEM (median diameter), twin defects observed by TEM, measuring the proportion of barium titanate more than 13%, lattice c / a is 1.0080 or more.
