High-weatherable titanium dioxide was prepared by inorganic and organic coating process, silicone was used as organic coating agent. The prepared samples were characterized by IR, XPS, TEM. According to the spectra of IR and XPS, it was found that silicone was bound on the surface of TiO2 particles. According to the spectra of TEM, it was found forming an organic coating layer. The temperature resistance experiments showed that the prepared high-weatherable titanium dioxide had good fluidity, and the heat-resistance temperature reached above 300 ℃.
