The theory of devitrification under diffusion controlled growth conditions, as in heavy metal fluoride glasses and aqueous solutions, is discussed and extended for nonisothermal transformations. Equations are given for nonisothermal devitrification which can be solved numerically or by making simplifying approximations to yield an equation which predicts the heating rate dependence of the devitrification temperature.
