متن کاملThe α–β phase transition in volcanic cristobalite
Cristobalite is a common mineral in volcanic ash produced from dome-forming eruptions. Assessment of the respiratory hazard posed by volcanic ash requires understanding the nature of the cristobalite it contains. Volcanic cristobalite contains coupled substitutions of Al3+ and Na+ for Si4+; similar co-substitutions in synthetic cristobalite are known to modify the crystal structure, affecting t...
متن کاملDetermination of cristobalite phase content in ceramic cores using various X-ray quantitative phase analysis methods
The aim of this research is to investigate different X-ray based quantitative phase analysis methods for determination of cristobalite phase content in ceramic cores. For this purpose, four popular routes including peak absolute intensity method, relative intensity ratio method, direct or calibration method and internal standard (or Alexander-Klug) method have been chosen. Some control samples ...
متن کاملPhase equilibria trigger for explosive volcanic eruptions
[1] A mechanism for explosive volcanic eruptions based on multicomponent phase equilibria modelling of four explosive volcanic systems is proposed. In each system, either isochoric or isobaric crystallization, where either crystals or crystals and exsolved fluid are chemically fractionated from melt, leads inevitably to near-solidus dynamical instability culminating in violent explosive eruptio...
متن کاملPhase Transition in the Macromolecules
It is well known that the functioning of biopolymers and primarily of proteins in a living cell is determined by a unique spatial ternary structure, this structure is called protein globule. It is also well known that when the protein is heated its denaturation occurs, the globular spatial structure is destroyed and the biochemical activity ceases. In this case one says that the globule is tran...
