| titleOfInvention | Method for preparing polycrystalline fibrous TiO2 pigment |
| abstract | A polycrystalline, fibrous rutile TiO2 pigmentary material having good optical properties and retention in paper, and exceptionally high tinting strength in latex paint systems is prepared by treating a substantially sulfate-free hydrous TiO2, prior to calcination, with a mineralizing complex comprising alkali metal and alkaline earth metal salts, a compound of boron and a rutile promoter sol, and calcining the treated hydrous TiO2 at temperatures in the ranges of from 812 DEG -865 DEG C. followed by washing to remove the calcium ions, milling, hydroclassification and drying; or optionally by a postcalcination treatment for imparting optimum pigmentary properties. |
