    • The present invention relates to a method a method for continuous preparation of a well dispersed spherical hydrous zirconia particles with an average diameter(dp) of 1˜1,000 nm in the form of sol solution, which method comprises continuously supplying the aqueous solution of a zirconium salt at a concentration of 0.001˜0.5 mole/l to a reactor consisting of one or more than two reaction tubes at a temperature of less than 25° C., heating the said aqueous solution in the reactor(s) in a continuous flow state up to the boiling point, and then discharging the said solution through the outlet of the said reactor(s). Contrary to the method employing a conventional batch-type reactor or semi-continuous stirred-type reactor, the method for continuous preparation of a hydrous zirconia sol according to the present invention can allow various operational parameters to be controlled in a certain range and thus contributes to remarkably improve the quality of a hydrous zirconia sol to be prepared or of the zirconia powder obtainable as a final product.
    • 本发明涉及一种连续制备溶胶溶液形式的平均直径(1〜1000nm)的分散良好的球形含水氧化锆颗粒的方法,该方法包括 在低于25℃的温度下将浓度为0.001〜0.5摩尔/升的锆盐水溶液连续供给到由一种或多于两种反应管组成的反应器中,加热反应器中的所述水溶液 (s)处于连续流动状态直到沸点,然后通过所述反应器的出口排出所述溶液。 与使用常规间歇式反应器或半连续搅拌式反应器的方法相反,根据本发明的连续制备含水氧化锆溶胶的方法可以使各种操作参数被控制在一定范围内,因此有助于 显着提高待制备的含水氧化锆溶胶的质量或作为最终产物获得的氧化锆粉末的质量。

    • The present invention relates to a method for continuous preparation of a hydrous zirconia sol dispersed by nanometer-sized spherical hydrous zirconia particles having an average diameter(dp) of 1˜250 nm, which method comprises supplying the aqueous solution of a zirconium salt at a concentration of 0.001-0.2 mole/l to a reactor consisting of one or more than two reaction tubes, and then irradiating microwave to the stream of the said aqueous solution in the reactor so that the said solution may be heated in a flow state. Contrary to the method employing a conventional batch-type reactor or semi-continuous stirred-type reactor, the method for continuous preparation of a hydrous zirconia sol according to the present invention can allow various operational parameters to be controlled in a certain range and thus contributes to remarkably improve the quality of a hydrous zirconia sol to be prepared or of the zirconia powder obtainable as a final product.
