The invention relates to a production method for a sodium stannate of ultra-low water soluble turbidity. The production method comprises the steps of: (1) putting stannous oxide into a sodium hydroxide solution and then adding hydrogen peroxide to prepare a sodium stannate solution; (2) sedimentating the prepared sodium stannate solution after heating; (3) performing natural filtration on the sedimentated solution to remove impurities; (4) adding a sodium acetate solution to the sodium stannate solution without impurities, performing heating concentration under a negative pressure condition, and performing cooling treatment, then adding hydrogen peroxide, after stirring the solution for a certain time, heating the solution again under the negative pressure condition for further concentration, and performing centrifugal separation; (5) drying the product under the negative pressure condition; and (6) crushing, screening and packaging the dried sodium stannate to obtain a sodium stannate product. The method provided by the invention is a simple and efficient production method for sodium stannate of ultra-low water soluble turbidity. The stannum content of the sodium stannate product prepared by virtue of the method is greater than 42% and the water soluble turbidity is stabilized at 5 degrees or below 5 degrees.
