AN ULTRA FINE BARIUM TITANATE BASED POWDER AND A METHOD FOR PRODUCING THE BARIUM TITANATE BASED POWDER BY OXALATE PROCESS

摘要

The present invention is a ferroelectric, piezoelectric, such as barium titanate powder used in various fields (barium titanate based powder), and relates to a method for producing it, and its object is to have a uniform particle size and the particle size of ultrafine barium titanate-based powder It is to want to provide.; The invention of ultrafine barium titanate-based powder and a manufacturing method having the following structural formula as a base.; [constitutional formula]; ABO ₃; [Wherein, O represents oxygen, A is Ba and Ba, and the additive which may be substituted with one or two paper sangyigo, B is Ti or Ti and one kind or two or more kinds sangyigo of additives which may be substituted, and A / B molar ratio of (mole ratio) 1 being;; According to the present invention, ultra fine and can be provided with a perovskite barium titanate powder which is excellent in dielectric properties it can be effectively used as a dielectric material such as a high-capacity MLCC ultrathin layer.
