【 摘 要 】

The current article describes the methods of producing titanium dioxide, or titania, which is used in various branches of the industry, including construction as a basis for producing white pigments. The base pigment grades of titania with their qualitative characteristics are listed, the modifying agents, applied in producing pigment grades, are presented, the several technologies of producing titania are mentioned. To obtain titania with different characteristics, various methods of treatment, viz. chemical or heat treatment, are used. To raise the material index of raw materials, used for producing titania and, simultaneously, to lower the obtaining of waste materials, several methods of obtaining titania from titanium slags and waste catalysts are offered. When applying the offered technologies, the range of the usage of titania will be expanded, and the efficiency of using raw materials will be increased.
