In this research, it is reported the result of crystallization kinetics
measurement of Fluoride(x) glass by using isothermal method of Differential
Thermal Analysis (DTA). Kinetics parameter of glass fluoride was determined by
applying Johnson-Mehl-Avrami formula. The analysis showed that the rate
constanta decreased by increasing crystallization temperature, time of half crystal
increased by increasing crystallization temperature. Moreover, it was also found
that activation energy was 5,52. J
