Extracting perovskite from high Ti-bearing blast furnace slag is a green and potential method to recover the second titanium resource. The non-isothermal crystallization process of perovskite in synthesized high titanium-bearing slag was studied in situ by confocal scanning laser microscope (CSLM) with cooling rate of -20K/min. The results showed that perovskite was the primary phase of the Ti-bearing synthesized slag (TiO2=23%) during cooling process. Perovskite precipitated at 1719K and finally presented orthogonal close straight lines morphology. Perovskite grew along a specific growth track that new particles precipitated successively in vertical and parallel way, with intersecting and hindering with each other.
