Fluoride-ion conducting solid materials are applicable as electrolytes for sensing devices and next-generation rechargeable batteries. Most of the previously reported have been limited to single-anion compounds such fluorite-type, tysonite-type, perovskite-type structures. These suffered from further improvements by crystal structure modification which derives a paradigm shift in material tailo...

DL_POLY_3 is a general purpose molecular dynamics (MD) simulation package designed to simulate systems of the order of tens of millions of particles and beyond by efficiently harnessing the power of modern computer clusters. Here we discuss the package design, functionality and report on performance and capability limits. We then report the application of DL_POLY_3 to study radiation cascades i...

The cause of coloration of Blue John fluorite from Castleton, Derbyshire, and blue banded fluorites from Ashover, Derbyshire, and Weardale, Co. Durham, has been investigated by a number of techniques, including mass spectrometry, optical spectroscopy, and paramagnetic resonance measurements on natural and irradiated samples. In all respects Blue John is indistinguishable from the other blue ban...

Fluorite has been attracting the attention of gemstone mineralogists because its rich color and excellent fluorescence properties. This paper studied fluorite with three types (blue, green, white) five blue-purple fluorites an alexandrite effect. Through study their structure, composition, spectral characteristics, gemological mineralogical characteristics coloration mechanisms different are co...

In the flotation of semi-soluble minerals such as calcite and fluorite, Ca2+ is one common dissolved components influencing collector adsorption behaviors on mineral surfaces. However, there very limited research focusing how affects separation fluorite calcite. study, with sodium oleate (NaOL) a tannic acid (TA) depressant, test, zeta potential measurement, experiment in presence were conducte...

TheZrO2-based materials are practically important as the thermal barrier coatings(TBC) for high temperature gas turbines, due to their low thermal conductivity, hightemperature thermal stability and excellent interfacial compatibility. Studies of the phaseequilibira, phase transformation, and thermodynamics of the ZrO2-based systems can providethe necessary basic knowledge t...

The original structure determination for aravaipaite, Pb3AlF9(H2O), indicated it to be monoclinic, P21/n, with a = 25.048(4), b = 5.8459(8), c = 5.6505(7) Å, β = 94.013(3)°, V = 829.7(2) Å3, and Z = 4. Examination of additional crystal fragments from the same specimen revealed that some have a triclinic cell, P1, with a = 5.6637(1), b = 5.8659(1), c = 12.7041(9) Å, α = 98.725(7)°, β = 94.020(7)...
