Abstract
TITANIUM DIOXIDE HYDRATE WHICH CONTAINS LESS THAN 250 PPM SULFATE IONS AND LESS THAN 50 PPM AMMONIUM OR ALKALI METAL IONS WITH RESPECT TO TIO2 IS OBTAINED BY PRODUCING AN AQUEOUS SUSPENSION WITH SULFATE-CONTAINING TITANIUM DIOXIDE HYDRATE WITH 2 TO 18BY CALCULATED AS TIO2, THE SULFATE CONTENT OF THE SUSPENSION CALCULATED AS H2SO4 IS DETERMINED, 95 TO 100.1 MOLOF THE STOCHIOMETRIC AMOUNT OF AMMONIA OR ALKALI METAL HYDROXIDE NECESSARY FOR THE NEUTRALIZATION OF THE CALCULATED H2SO4 AMOUNT IS ADDED UNDER S RRING PERIOD OF 5 TO 60 MINUTES, PREFERABLY 10 TO 30 MINUTES, AND IS WASHED WITH LOW-SALT, PREFERABLY DEIONIZED, WATER AND A DIFFUSION WASH WITH DEIONIZED WATER IS CARRIED OUT AT A PRESSURE OF 3 TO 5 BAR THEN PERFORMED.
