A lot of industrial products require TiO2 starting materials with well-defined properties for specific applications. Some of the most important of these grades of titanium dioxide are those with a high specific surface area, a small particle size, and very high reactivity. Specific requirements often exist regarding purity and property consistency. The most important applications for nonpigmentary TiO2 are vitreous enamels, glass and glass ceramics, electroceramics, catalysts and catalyst supports, welding fluxes, colored pigments, electrical conductors, chemical intermediates (e. g., potassium fluorotitanate), structural ceramics, UV absorbers, and refractory coatings [2.68].
