Spinel concentration in MS-7 glass (0% others) with its limited components shows to be dependent on several variable properties during heat treatments, primarily the limited number of nucleation sites and the growth rate of spinel. Equilibrium seems to be unaffected by this phenomenon, but the kinetics of spinel crystallization show a dependence. An empirical relationship between the number density (ns) of spinel in glass and the rate constant (k) in the Avrami equation was established showing that the kinetics of crystallization are temperature (T) and ns dependent.
