Beschreibung
Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: modification of titanium dioxide by metal oxides involves titanium dioxide treatment in water suspension by solutions of magnesium, or aluminium, or nickel formiates obtained by reaction of aqueous formic acid solution with the indicated metals or their carbonates or hydroxides. Formic acid quantity is stechiometric or exceeds stechiometric quantity by 20-100%. Further the suspension is dried in dispersion dryer with heating of titanium dioxide with applied salts at 200-700°C for 1-60 minutes. ^ EFFECT: reduced temperature of titanium dioxide modification without surface contamination with hardly removable anions, or anatase form transmutation into rutile form. ^ 2 cl, 9 ex
