We report investigation of structural phase transitions in technologically important material sodium niobate as a function of temperature on heating over 300-1075 K. Our high resolution powder neutron...
Non-convergent cation ordering in the (Fe O ) (MgAl O ) solid solution was investigated us- ing in-situ time-of-flight neutron powder diffraction. The approach to equilibrium in a sample with x = 0...

Thestructure oflizardite-l Tfrom MonteFico,Elba,wasrefined in spacegroupP31m usingneutron diffractiondata, measuredat 8, 150,and 294K,and full-profile Rietveld refinement techniques. Thelattice param...
A monoclinic IIb-2 clinochlore from the Achmatov mine, Ural Mountains, U.S.S.R., was investigated by neutron diffraction. The formula, based on electron microprobe and wet chemical analyses, is (Mg4.5...
Abstract: Neutron diffraction measurements for a preferentially oriented aggregate slab sample of deuterated Na-montmorillonite from Upton, Wyoming, are described for a series of clay-water contents r...
Abstract: The use of neutron diffraction to determine some of the structural properties of montmorillonite-water systems at low water concentrations is described. The samples were prepared by compress...
