Abstract
DSC ( differential scanning calorimetry ) was used to measure the induction time of the polymorphic transition from the high temperature phase of silver selenide (Ag_2Se). Induction times became longer for smaller supercooling. Experimental results were analyzed by an equation introduced by Toschev, τ=(1/A)exp(B/ΔT^2) , where A and B were constants and AT was supercooling.
