Quartz single crystal thermal diffusivity measurements by laser flash method: from -120 °C through the α-β phase transition to 800 °C Simon Breuer and Frank R. Schilling https://doi.org/10.5445/IR/1000119716

Short summary

The knowledge of physical properties of quartz as an abundant rock-forming mineral in the Earth’s crust allows for a better understanding of its dynamic processes. The thermal transport properties of single-crystal quartz are studied between –120 °C and 800 °C using a laser flash method. First, low-temperature data as well as the role of the low-to-high quartz phase transition (e.g. a transition-related non-ballistic radiative transfer) and size effects on thermal diffusivity are discussed.
