Abstract

Anatase and rutile powders prepared by various methods were characterized by thermoanalytical studies up to 1400 °C using a simultaneous TG-DTG-DTA apparatus. Preparation techniques were developed for the manufacture of amorphous titania, pure anatase, stabilized anatase and pure rutile.

Enthalpy effects originating from the crystallization of amorphous parts into the anatase modification and from the phase transition of anatase into rutile were investigated.

The latter phase transition was detected by means of heat flux DSC measurements. The transition enthalpy was determined.

Zusammenfassung

Nach verschiedenen Methoden dargestellte Anatas- und Rutil-Pulver wurden mittels simultaner TG-DSC bis 1400 °C charakterisiert. Die Präparationsmethoden lieferten amorphes Titan(IV)-oxid, reinen Anatas, stabilisierten Anatas und reinen Rutil. Die Enthalpieeffekte infolge der Kristallisation amorphen Materials zu Anatas und der Phasenumwandlung von Anatas in Rutil wurden untersucht. Mittels Wärmefluss-DSC wurde letztere Umwandlung nachgewiesen und ihre Enthalpie bestimmt.

Резюме

Полученные различны ми методами порошкообразные ана таз и рутил были изуче ны совмещенным методом ТГ-ДТГ и ДТА до темпера туры 1400°. Разработаны методы п олучения аморфной окиси титан а, чистого анатаза, стабилизированного анятаза и чистого рут ила. Исследованы энтальп ийные эффекты процес са кристаллизации амор фных участков на анат азе и фазового превращен ия анатаза на рутиле. Э тот фазовый переход был также обн аружен методом ДСК тепловог о потока., Определена э нтальпия этого перехода.
