Abstract：In order to explore the effects of different contents of TiO2 on the sintering properties of high titanium vanadium-titanium magnetite， the current study adopted titanium concentrate whose size distribution and compositions were similar to that of Panzhihua concentrates to vary [w(TiO2)]. The design could eliminate the effects of the change of particle size in the sintered material on the experimental results， which could truly reflect the influence of TiO2 well. Main results show that under the condition of high alkalinity of sinter and the same compositions， when the [w(TiO2)]in sinter increased from 6% to 10%， both the initial melting temperature and the melting temperature increased， the strength and yield of sinter decreased， the reduction powdered ratio of sinter in low temperature rose， and the reducibility and the droplet property became worse. While the storage performance of sinter had little change. On the other hand， the contents of hematite titanium iron and calcium ferrite decreased， the contents of titaniferous magnetite and titanium mineral perovskite， titanium pyroxene， garnet titanium increased. The hole number in sinter increased， and the mineral morphology and structure became worse.
