抄録

The crystallization of wollastonite-type, (Ca, Mg, Fe)SiO3, in the system of Al2O3-CaO-Fe2O3-K2O-MgO-MnO2-Na2O-P2O5-SiO2-TiO2 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 determined to be 222.20 kJ•mol-1.<br>
