Abstrakty
Precipitation of titania using titanium(IV) sulphate(VI) as the precursor in the emulsion system has been studied. Tytanpol® R-210 of the rutile type structure was used as a standard. The basic physicochemical parameters of the titanium dioxide such as bulk density, the absorption capacity of water, paraffin oil and dibutyl phthalate have been determined along with the moisture content and oil number. Morphology and dispersive characteristics of the titanium dioxide precipitated have been evaluated by the SEM and NIBS techniques. The TiO2 powders have been also studied by XRD and colorimetric method. In the emulsion system proposed titania of rutile structure has been successfully precipitated. It has been established that the properties of the titanium dioxide obtained depend not only on the composition of the emulsion but also on the amount of the emulsifier applied.
Przeprowadzono badania nad strącaniem bieli tytanowej w układzie emulsyjnym. Wzorcowym ditlenkiem tytanu był Tytanpol® R-210 produkowany przez Zakłady Chemiczne Police S.A. Oznaczano podstawowe parametry fizykochemiczne strąconych próbek ditlenku tytanu, takie jak: chłonności wody, oleju parafinowego i ftalanu dibutylu oraz gęstość nasypową, a także zawartość wilgoci i liczbę olejową. Określano morfologię i mikrostrukturę otrzymanego ditlenku tytanu w celu uzyskania informacji o dyspersji, morfologii ziaren oraz budowie poszczególnych cząstek, wykorzystując techniki SEM i NIBS. Ponadto strącone próbki poddano analizie rentgenograficznej i kolorymetrycznej.
