Description

technical field [0001] The invention belongs to the field of nano powder material manufacture, and relates to a device and method for preparing high-purity barium titanate. Background technique [0002] In recent years, driven by the trend of device miniaturization (high integration requirements of microelectronic devices, such as multilayer ceramic capacitors MLCC), nano-BaTiO 3 The performance of the material has been improved. High-performance MLCC requires high-quality dielectric constant and ultra-fine BaTiO with high-purity, homogeneous, and weakly agglomerated particles with small and uniform sizes 3 Based ceramic powder particles, the performance can be improved by reducing the thickness of the ceramic layer. The hydrothermal synthesis preparation method of barium titanate powder is an important industrial process method, which can prepare ultra-fine ceramic dielectric layers suitable for MLCC, PTC and other technologies. [0003] Traditional BaTiO 3 Nanoparticle...
