Phase transformation in the system kaolinite/nano-TiO2 during the heating up to 1300°C
Original language description
Composites based on the TiO2 nanoparticles captured on the kaolinite surface comprise two major advantages: i) TiO2 nanoparticles ensure the photocatalytical activity of this composite, ii) kaolinite to metakaolinite phase transformation ensure latent hydraulic properties of the heat treated kaolinite/TiO2 composite. During the thermal treatment up to 1300°C, the composite undergo three major phase transitions. The temperatures at which the transformations occur cover wide range according to amount of the TiO2 and amount of the sulfur. At lower temperatures - approx. 500 - 800°C the dehydroxylation of kaolinite and formation of metakaolinite occurs, at the temperature range of 700 - 1300°C the transformation of anatase to rutile occurs (depending on the amount of TiO2), and at the temperature range of 900 - 1000°C the formation of mullite occurs. The phase transformations were studied using X-ray powder diffraction method, infrared spectroscopy, and specific surface area of the calcine
