NPO energy storage dielectric ceramic material, preparation method and application thereof
The invention belongs to the technical field of energy storage ceramic materials, and particularly relates to an NPO energy storage dielectric ceramic material and a preparation method and application thereof. According to the preparation method, manganese-doped NPO powder is prepared by adopting a solid-phase reaction method, and the manganese-doped NPO energy storage dielectric ceramic material is prepared by sintering; the thickness of the prepared manganese-doped NPO energy storage dielectric ceramic sheet material is within the range of 1.30-1.60 mm, the grain size distribution is uniform, and the compactness degree is good; the prepared fine-grain energy-storage ceramic capacitor dielectric material has the advantages that the room-temperature dielectric constant reaches 120 or above, and the compression strength is higher; the dielectric loss of the fine-grain energy-storage ceramic capacitor dielectric material prepared by the invention is only 0.0004, so that the dielectric loss is small; the prepared ceramic is uniform in particle size, high in reliability and suitable for being used for producing a ceramic energy storage capacitor with a large-capacity and ultrathin dielectric layer.
