Study on the stability of GaF3-based glasses by differential scanning calorimetry

The glass formation and devitrification of GaF3-based glasses were studied by differential scanning calorimetry. A comparison of various simple quantitative methods to assess the level of stability of multi-component fluoride glass systems is presented. Most of these methods are based on critical temperatures. In this paper a new parameter kb(T) is added to the stability criteria. The stability of several GaF3-based glasses were experimentally evaluated and correlated with the activation energies of crystallization via this new kinetic criterion and compared with those evaluated by other criteria.

Recognition on systems RbF-GaF3 and CsF-GaF3

The systems RbF-GaF3 and CsF-GaF3 were re-investigated by DTA and XRD method. In the system RbF-GaF3, with eutectic E1 at 750°C in the location of 8.5 mol% GaF3 and E2 at 749°C in the location of 43.0 mol% GaF3, three compounds Rb3GaF6, RbGaF4 and RbF·2GaF3 were identified and indexed by XRD. The indexed result of α-Rb3GaF6 could not be successfully obtained, β-Rb3GaF6 is tetragonal, a = 6.324±0.004, c = 8.860±0.003 A?. RbGaF4 is orthorhombic, a = 9.821 ± 0.006, b = 9.517 ± 0.005, c = 8.060 ± 0.006 A?; RbF·2GaF3 is also orthorhombic, a = 9.459 ± 0.005, b = 9.336 ± 0.005, c = 7.685 ± 0.005 A?. In the system CsF-GaF3, with eutectic E1 at 66C in the location of 7.5 mol% GaF3 and E2 at 675°C in the position of 44.0 mol% GaF3, two compounds were confirmed. α-Cs3GaF6 is orthorhombic with a = 10.62 ± 0.02, b = 9.959 ± 0.006 and c = 5.607 ± 0.005 A?; β-Cs3GaF6 is also orthorhombic, a = 10.356 ± 0.003, b = 8.280 ± 0.003, c = 7.621 ± 0.005 A?; γ-Cs3GaF6 is tetragonal, a = 6.833 ± 0.003, c = 9.869 ± 0.002 A?; CsGaF4 is orthorhombic, a = 8.571 ± 0.007, b = 7.575 ± 0.007 and c = 6.981 ± 0.006 A?.

Structural and magnetochemical studies of Ba5Mn3F19 and related compounds AII5MIII3F19

Single crystal structure determinations by X-ray methods were performed at the following compounds, crystallizing tetragonally body-centred (Z = 4): Sr5V3F19 (a = 1423.4(2), c = 728.9(1) pm), Sr5Cr3F19 (a = 1423.5(2), c = 728.1(1) pm), Ba5Mn3F19 (a =1468.9(1), c =770.3(1) pm, Ba5Fe3F19 (a =1483.5(1), c =766.7 (1) pm), and Ba5Ga3F19 (a = 1466.0(2), c = 760.1(2) pm). Only Ba5Mn3F19 was refined in space group I4cm (mean distances for elongated octahedra Mn1-F: 185/207pm equatorial/axial; for compressed octahedra Mn2-F: 199/182 pm), the remaining compounds in space group I4/m. In all cases the octahedral ligand spheres of the M1 atoms showed disorder, the [M1F6] octahedra being connected into chains in one part of the compounds and into dimers in the other. The magnetic properties of the V, Cr and Mn compounds named above and of Pb5Mn3F19 and Sr5Fe3F19 as well were studied; the results are discussed in context with the in part problematic structures.
