<p>A stabilised anatase suspension for use in paper manufacture has a total solids content of 60-82% wt. and contains, as a first fraction 19-38% TiO2 (relative to total TiO2 in suspension) 0.3-3.0% Al2O3 (relative to first TiO2 fraction), a second TiO2 fraction in amt. sufficient to give desired total TiO2 contains 0.1-0.2% triethanolamine (relative to second TiO2 fraction), 0.01-0.1% Na-polyphosphate (relative to total TiO2) 0.1-2% of a second alkanolamine (relative to total TiO2) and suffic. water to form a suspension contg. 60-82% solids.</p> |
