Abstract

Studies of the reactivity of six TiO2 samples (two rutiles and four anatases) and nine carbon samples towards the formation of TiN by reduction of TiO2 with carbon in a nitrogen atmosphere at 1150°C show that the reaction is influenced by the chemical and physical properties of both the TiO2 and the carbon. Although anatases and rutiles behave similarly, their reactivities are adversely affected by the presence of impurities such as those deliberately added as surface coatings in pigment-grade TiO2. There is some evidence that the reactivity of the TiO2 increases with increasing surface area. Carbons with higher ash contents appear to be more reactive. The reactivity of the carbons generally increases with increasing surface area, as measured by gas penetration methods (BET nitrogen adsorption and Blaine gas permeation).
