Acoustic Emission During Firing of the Illite-Based Ceramics with Fly Ash Addition

Popis výsledku v původním jazyce

In this work, illite-based ceramic body with power plant fly ash addition (60 wt.% of illite, 30 wt.% of fly ash and 10 wt.% of illite fired at 1100 degrees C) was investigated by the thermal analysis techniques (differential thermal analysis, thermodilatometry and thermogravimetry) and the acoustic emission technique. The green body was heated up to 1100 degrees C at three different rates 2.5, 5, 10 K/min. The most intense acoustic emission was recorded at the highest rate 10 K/min. Mutual correlationsbetween thermal analyses and acoustic emission data were also examined. The first acoustic emission response appears at 430 degrees C, corresponding to a small endotherm on the DTA curve, where the thermal decomposition of mineral portlandite takes place. In the temperature range from 600 to 900 degrees C, high acoustic emission activity correlates with dehydroxylation and expansion of the sample. At temperatures higher than 800 degrees C, the source of acoustic emission signals is the
