Application of Acoustic Emission Method to Thermal Analysis

摘要

A new technique for simultaneous acoustic emission (AE) and differential thermal analysis (DTA) measurement is described. The technique has been successfully utilized to monitor some mechanical events occurring during dehydration, decomposition, and phase transition of NaN_3, alkali perchlorate (MeClO_4 where Me=Na, K, Cs), CsCl, NH_4Cl, NH_4Br, and KNO_3 for which the new results are reported. It is noticed that the events which cannot be detected by DTA are monitored by AE.
