The crystallization of wollastonite-type, (Ca, Mg, Fe) SiO_3, in the system of Al_2O_3-CaO-Fe_2O_3-K_2O-MgO-MnO_2-Na_2O-P_2O_5-SiO_2-TiO_2 has been studied over the temperature range of 1148-1348 K. A linear growth rate of surface crystallization of the wollastonite-type has been observed for the glass system. The crystal growth rate was measured as a function of temperature in a platinum crucible contact regime where heterogeneous crystal has been found to occur. The beginning of the crystallized-layer growth was preceded by a considerable induction period. The activation energy barrier for crystallization of the wollastonite-type at large undercoolings was deter-mined to be 222.20 kJ-mol^<-1>.
