Alpha quartzM.M.J. TreacyJ.B. HigginsCollection of Simulated XRD Powder Patterns for Zeolites (Fifth Edition)
Crystallography of alpha-quartz is discussed with special reference to the existing ambiguities regarding handedness of its enantiomorphic forms and a mnemonic has been suggested. Previous x-ray diffraction topographic studies of synthetic quartz are critically reviewed and analysed to understand the ...
This chapter presents the numerical data and the simulated powder patterns of Alpha Quartz material with 39.49° as 2θ value. Two compositions, which are expressed in terms of the full unit cell content, are provided. The chemical composition is the nominal material composition provided in the ...
