The crystal structure and its relation to the chemical composition will be investigated for two specific groups:(a) Zeolites are porous tetrahedral framework structures containing additional extraframework water and cations in channels and cages. Various zeolite minerals will be "in situ" dehydrated by stepwise heating until structural breakdown occurs. The influence of heat treatment associated with partial dehydration upon the structural framework will be monitored by single-crystal X-ray diffraction methods (PhD project).(b) Calcium silicates and related minerals with additional components, analogues to crystalline components in cements and ceramic materials, are found in nature in larger crystals than in technical products. This enables structural characterization of technological important crystalline materials. Corresponding crystals will be isolated from CaO-SiO2 rich rock samples and structurally analyzed applying single-crystal X-ray diffraction methods (PhD project).
