Fission tracks in natural CaF2 were analysed by chemical etching [19], and tracks created by bombardment with cluster ions of several tens MeV were investigated also by TEM [10], [20]. After exposure to ion irradiation, damage in fluorite nanopowder was analysed by X-ray diffraction [21] ...
Phases with variable composition having the fluorite structure which are formed in the MFn,-RF0, type systems (m, n -4) [1, 2] are a are example of ionic compounds that allow anomalously high contents of structural de-fects -vacancies and incorporated atoms. In the MI_xRXF2+X phases ...
A universal cluster model (UCM) of a defect (cluster) structure was developed on examples of nanostructured nonstoichiometric crystals (NNCs) M1鈭抶RxF2+x (M = Ca, Sr, Ba; R = La鈥揕u, Y) of the fluorite type (CaF2). This family of NNCs ... EA Sulyanova,BP Sobolev - 《Crysten...
Here we report on the successful realization of superconducting SmO1−xFxFeAs oxypnictide thin film growth by in-situ PLD on CaF2 (fluorite) substrates. CaF2 acts as fluorine supplier by diffusion and thus enables superconducting oxypnictide thin film growth by PLD. Films are grown ...
We tried to insert the conductive ITO layers between YHO-7 and YSZ single crystal having fluorite structure. ITO has a bixbyite structure as illustrated in Fig. 1(b) and is often used as an oxide electrode because of its good conductivity and excellent optical transparency. Here, we focus...
The lowest RI of the aforementioned glasses is that of fused quartz (RI = 1.450); nevertheless, the RI of calcium fluoride (CaF2) glass is even lower at 1.434 (Malitson1963). Given this RI, as well as its insolubility in water, CaF2appears as excellent RIM candidate for use in aqueous...

the superionic conductors that show a Faraday transition – the continuous increase in the ionic conductivity over a range of temperatures – the fluorite structures have enjoyed incisive examinations over the past four decades; yet the fundamental nature of superionicity has remained largely inconclusive...
