Abstract

Abstract

The industrial technologies of tetragonal barium titanate mainly include solid-state method and hydrothermal synthesis method, but there are problems such as large particles, uneven particle size distribution, and low tetragonal phase content. Tetragonal barium titanate was successfully prepared by microchannel synthesis method using barium chloride, titanium chloride, and oxalic acid as raw materials, as well as compared with traditional co-precipitation method. The results of XRD, SEM and TEM indicate that the product is a high-purity, small particle size, and uniformly distributed tetragonal barium titanate, with an average particle size of 110 nm and a particle size distribution range of ± 16 nm. This method with simple synthesis process is easy to achieve mass production and lays the industrial production of high-purity and small-sized tetragonal barium titanate.
