Abstract

Abstract

In this paper, the titanium dioxide filter cakes after zinc or aluminum salt treatment from a titanium dioxide factory in Panzhihua were selected as test materials to study the properties of titanium dioxide particles during the calcination process from room temperature to 990 ℃ under the condition of constant heating rate. Firstly, the moisture changes of the samples at different temperatures during calcination were analyzed by moisture analyzer. The results showed that there was basically no structural dehydration above 800 ℃. The morphology and particle size of the particles were further investigated by ZS90 and SEM, which showed that the aggregates with clear boundaries were formed first in the process of dehydration. After complete dehydration, the aggregates gradually disintegrated, and the primary particles gradually grew and the boundaries became clear. When the rutile content reaches more than 98%, the SEM average particle size of TiO₂ particles increases with the increase of temperature, and the standard deviation of particle size also increases. The effect of desulfurization on the zeta potential on the surface of TiO₂ particles is more obvious than that of dehydration, and the change of rutile content has a significant effect on the change of the zeta potential on the surface of the particles.
