Non-isothermal crystallization kinetics of La2CaB10O19 from glass

► Crystallization kinetics of the nonlinear optical phase La2CaB10O19 from glass. ► Kinetic parameters (Johnson-Mehl-Avrami) estimated by multiple analysis methods. ► La2CaB10O19 crystallizes from a nuclei site-saturated glass matrix. ► Crystallization mechanism with a three dimensional and interface controlled growth. ► Avrami exponent and morphology index were found to be n= = m = 3.
