Title:
有益な性質を有する酸化チタン粒子およびその製造方法
Document Type and Number:
Japanese Patent JP4546834
Kind Code:
B2
Abstract:
Titanium dioxide particles having a selective shielding effect against infrared radiation and a high spreadability are disclosed. The titanium dioxide particles have a primary particle size of 0.5 to 2.0 mum and a visible light transmission of less than 95%. The titanium oxide particles consist essentially of 0.05 to 0.4% by weight of aluminum oxide, 0.1 to 0.8% by weight of zinc oxide, and the balance of titanium dioxide. The titanium dioxide particles are produced by blending of hydrated titanium oxide with minor amounts of an aluminum compound, a zinc compound and a potassium compound, and then calcining the blend.
