Abstract

Physico-chemical methods analysis (DTA, RSA, AES) was used for research of phase formation and interaction in the system TiO₂(anatase) –NiO. It has been shown, that addition of NiO appreciably reduces the temperature of heat treatment and time of recrystallization of anatase to rutile. At temperatures about 700-850 С two processes go on simultaneously: formation of NiTiO₃and phase formation of anatase into rutile. It is necessary to note, that interaction of anatase and rutile modification of TiO₂ with NiO is various. It was experimentally established that formation titanata nickel depends on way of the reception both oxides of titanium, and oxides of the nickel. So, change of anatase on GDT promotes formation of NiTiO_3.
