Nano-barium sulfate was prepared by ultrasonic method.The influnces of the concentration of reactant,ultrasonic power, reaction time, reaction temperature on the particle size of the product were investigated, and a laser particle size analyzer and TEM analysis and characterization were carried out.The results showed that when the ultrasonic power ratio was 40%, concentration of reactant was 0.25 mol/L, ultrasonic reaction time was 15 min, ultrasonic reaction temperature was 30 ℃,the size of barium sulfate was the smallest.
