摘要：

ESR studies on solid solutions of vanadium ions in a TiO2 rutile matrix show the presence of small amounts of V3+ ions beside V4+ ions. Heating in oxygen at 370°C and 450°C leads to oxidation of V3+ to V4+, the latter ions being however resistant to oxidation. The concentration of V3+ practically does not change upon treatment of the solid solutions by o-xylene-air mixtures at 400°C. © 1979 Akadémiai Kiadó.
