Abstract

Talc/TiO2 composite particle was prepared with TiO2 coating on the surfaces of the talc particles by mechano-chemical method. X-ray diffraction (XRD) and scanning electron microscope (SEM) were used to investigate the microstructures and morphologies of the composite particles. The mechanism of the mechano-chemical reaction was researched by infrared spectra (IR) and X-ray photoelectron spectroscopy (XPS). The prepared talc/TiO2 composite particle has similar pigment properties compared with TiO2, with its hiding power 10.45g/cm3 and whiteness 97.49%. The results show that TiO2 coated evenly on the surfaces of the talc particles by Si–O–Ti and Mg–O–Ti bonds through surface dehydroxylation reaction.
