Abstract
Quartz in traditional ceramics brings about microcracking during firing due to its modification transition at 573 °C. The resulting microcracks are usually studied after firing by optical methods.
Therefore, the exact temperature at which the microcracking occurs is unknown, and hence, the underlying conditions cannot be identified. In this study, in situ measurements of Young's modulus (YM) and acoustic emission (AE) were used for studying cracking in the temperature region around the α LEFT RIGHT ARROW β quartz transition.
