Verification of an Analytical Method for Measuring Crystal Nucleation Rates in Glasses from DTA Data
A recently proposed analytical (DTA) method for estimating the nucleation rates in glasses has been evaluated by comparing experimental data with numerically computed nucleation rates for a model lithium disilicate glass. The time and temperature dependent nucleation rates were predicted using the model and compared with those values extracted from an analysis of numerically calculated DTA curves. The validity of the numerical approach was demonstrated earlier by a comparison with experimental data. The excellent agreement between the nucleation rates from the model calculations and the computer generated DTA data demonstrates the validity of the proposed analytical DTA method.
