In previous papers [1–3] methods for evaluating the kinetic parameters of crystal growth in inorganic glasses from DTA curves were proposed by the authors. These methods were used to study the devitrification kinetics of different glass systems and the results were in good agreement with those obtained by alternative methods. In this paper the non-isothermal devitrification of NaP03 glass has been studied in order to show that in some cases two different interpretations can be drawn from the experimental DTA results. It has been shown that the correct interpretation can be selected if SEM investigations are also carried out.

Abstract
In previous papers [1–3] methods for evaluating the kinetic parameters of crystal growth in inorganic glasses from DTA curves were proposed by the authors. These methods were used to study the devitrification kinetics of different glass systems and the results were in good agreement with those obtained by alternative methods. In this paper the non-isothermal devitrification of NaP03 glass has been studied in order to show that in some cases two different interpretations can be drawn from the experimental DTA results. It has been shown that the correct interpretation can be selected if SEM investigations are also carried out.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
