Incommensurate structure of Ca2Al2O5 at high temperatures--structure investigation and Raman spectroscopy
{{output}}
A high-temperature X-ray diffraction study revealed that brownmillerite-type Ca(2)Al(2)O(5) transforms to an incommensurately modulated structure at elevated temperatures. Single crystals of Ca(2)Al(2)O(5) were synthesized in an end-loaded piston cylinder pres... ...
