TRANSIENT NUCLEATION RATE IN OXIDE GLASSES

Abstract

Nucleation is the formation of a mutation on which the crystal structure develops. Out of the two main types of nucleation, this study focuses on homogeneous nucleation. In the nucleation theory, nucleation is described as the spontaneous growth of the cluster where attachment and detachment occur simultaneously. Once the cluster has reached a size greater than the critical size, we call it a nuclei. Hence, this development of clutter is time-dependent until it reaches a steady state distribution. The time-dependent component is the transient nucleation, and the time-independent cluster formation rate is called steady state nucleation rate. In this study, we used differential thermal analysis to study the transient nucleation for longer times of cluster formation (nucleation times). Adding to the ongoing controversial discussions, our study indicates that the transient nucleation is longer than previously assumed.
