%X In order to promote the enrichment of titanium component in perovskite phase, based on the technology of selective precipitation, the slag is supposed to be oxidized. In this work, the non-isothermal precipitating behavior of perovskite phase in oxidized titanium bearing slag was studied by quenching method, and the precipitating process kinetics of perovskite phase was analyzed. The results show that the precipitating of perovskite phase is related to the cooling rate, i.e. the lower the cooling rate, the higher the volume fraction of perovskite phase. The precipitation kinetics of perovskite phase can be approximately described by the JMAK equation.
