Process for improving pigmentary metal oxides |
| abstract |
PIGMENTARY METAL OXIDES, PARTICULARLY TITANIUM DIOXIDE, ARE PREPARED BY VAPOR PHASE OXIDATION OF CORRESPONDING METAL HALIDES. A METHOD FOR WET TREATING RAW METAL OXIDE TO IMPROVE PIGMENTARY PROPERTIES IS DESCRIBED. THE PROCESS COMPRISES DIGESTING AN AQUEOUS SLURRY CONSISTING ESSENTIALLY OF SUCH OXIDE AT PH LEVELS BELOW 2.0 AND AT TEMPERATURES OF FROM 50*C. TO THE BOILING POINT OF THE SLURRY FOR A PERIOD OF TIME SUFFICIENT TO REDUCE THE SURFACE ACTIVITY OF THE RAW METAL OXIDE. |
