COATING OF TITANIUM DIOXIDE COATINGS AND METHODS OF FORMATION OF TITANIUM DIOXIDE with decreasing size of the crystals

摘要

FIELD: metallurgy.;SUBSTANCE: sol-gel compositions re made to be applied onto substrate. Said substrate is heated at temperature necessary for forming coating from titanium dioxide with crystallite size smaller than 35 nm. Proposed coating features better antibacterial properties, self-purification and/or wetting ability.;EFFECT: higher photo catalytic activity.;18 cl, 8 dwg, 5 ex
