Structural behavior, crystal chemistry, and phase transitions in substituted leucite: High-resolution neutron powder diffraction studies
Structural behavior crystal chemistry phase transitions substituted leucite High-resolution neutron powder diffraction studies
2012/4/1
High-resolution neutron powder diffraction was used to study phase transitions in theleucite phases of KAlSi206, RbAlSi20", CsAlSi206, and KFeSi206. Thetemperature-depen-dent structural behavior invol...

Artifacts Illite/smectite Powder X-ray diffraction Sample preparation Turbostratic X-ray coherence
2011/12/31
X-ray diffraction patterns were obtained from rock fragments, < 1 祄 randomly oriented freeze-dried powders, and < 1 祄 oriented aggregates for 11 mixed-layered illite/smectite samples (K-bentonites) th...
X-ray Powder Diffraction Studies on the Rehydration Properties of Beidellite
Beidellite Cation migration Dehydration Fourier analysis Interlayer ration Rehydration X-ray powder diffraction
