Abstract CRYSTALISATION STUDY OF FLUORIDE(X) GLASS WITH ISOTHERMAL METHOD USING DIFFERENTIAL THERMAL ANALYSIS (DTA) By WAHYU BUDI UTOMO M0200051 Physics Departement Sebelas Maret university Surakarta 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 26 10- . (key words: crystallization, Fluoride, Differential Thermal Analysis)
