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...
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...
Abstract: The rehydration properties of Ca-, Mg-, Na-, and K-saturated homoionic beidellites after heating at various temperatures were compared with those of montmorillonites. The behavior of interla...
Highly significant differences are observed between the methyl derivatives of attapulgite, produced when this mineral is reacted with (CH3)2Si(OC2H5)2, in the presence or in absence of HCl. In the fir...
