Titanium oxide particles, which selectively shield infrared rays and have high sliding properties, are disclosed. The titanium oxide particles have a primary particle diameter of 0.5 to 2.0 µm, a visible light reflectance of less than 95%, 0.05 to 0.4 wt% aluminum oxide, 0.1 to 0.8 wt% zinc oxide, and the remaining titanium oxide. Is done. These titanium oxide particles are produced by mixing a small proportion of aluminum compounds, zinc compounds and potassium compounds with hydrous titanium oxide, and roasting the mixture.n n n n Titanium oxide, visible light reflectance infrared shielding, improved sliding |
