摘　　要：四方相钛酸钡的工业生产方法主要为固相法和水热合成法,但存在颗粒大、粒径分布不均匀及四方相含量低等问题。以氯化钡、氯化钛和草酸为原料,采用微通道合成法成功制备了四方相钛酸钡粉末,并与传统共沉淀法进行了对比。XRD、SEM及TEM结果均表明,以微通道合成法制备的产品纯度更高、粒径更小、颗粒分布更均匀,其平均粒径可达110 nm左右,粒径分布范围仅为±16 nm。该方法工艺简单、易于实现批量生产,为高纯度、小尺寸四方相钛酸钡的工业化生产奠定基础。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.
