Abstract

The present invention discloses a nanometer barium titanate powder preparation method based on ball milling. According to the method, barium oxide, titanium oxide, zirconium oxide grinding ball, and deionized water are added to a ball mill to carry out a chemical reaction under a ball milling condition, and the mixture obtained from the reaction is sequentially subjected to filtration separation, drying, and grinding crushing to obtain the tetragonal phase nanometer barium titanate powder. According to the present invention, the tetragonal phase nanometer barium titanate powder prepared through the method has characteristics of high purity, small particle size, uniform particle, and good dispersion, wherein the average particle size of the powder is within 60-80 nm; and the preparation process does not require the addition of any other chemical solvents, has advantages of no requirement of calcining, simple process, inexpensive equipment, easy operation, low energy consumption, and the like, and provides good industrial prospects in the field of electronic ceramic material preparation.
