%X Glass-ceramic made from blast furnace slag was studied.Glass-ceramic samples were produced by changing the content of TiO_2 as nucleation-agent in the parent glass,and the samples were analyzed by a differential thermal analyzer(DTA)at different heating rates.Based on heating rate and the peak crystallization temperatures from the DTA curves,three different methods were used to calculate crystallization activation energy of glass-ceramic samples.The results showed that as TiO_2 content increased,the values of activation energy first decreased,then increased.When the content of TiO_2 was 3.1%,the activation energy was the lowest,135.7,143.9, or 151.7 kJ/mol,as calculated by the three different methods.Infrared spectra showed that the crystallization was the easiest when the content of TiO_2 was between 3% and 4%.X-ray diffraction analysis showed that when the content of TiO_2 was between 3% and 4%,the formed glass-ceramic had the crystal phases of diopside as main phase and rutile as subordinate crystal phase.
