Procedure

The above sodium citrate solution was added to 500 g of zirconium hydroxychloride solution which contains 20.0% ZrO2. The reaction batch was mixed continuously while the sodium citrate was being added. A clear solution of sodium zirconium citrate was obtained after the addition of sodium citrate solution was completed. The pH of the solution product was 6.2.
