2Conduction properties of condensed lanthanum phosphates:La(PO_3)_3 and LaP_5O_(14)显示文摘Single crystals of LaP3O9·3H2O were prepared using a classical method of aqueous chemistry whereas those of the ultraphosphate LaP5O14 were obtained by flux method.Thermal treatment of LaP3O9·3H2O up to 700 °C allowed us to obtain the lanthanum polyphosphate La(PO3)3.The conductivity as well as the vibrational study of the lanthanum ultraphosphate and polyphosphate were analysed in order to explain the mechanism of conduction.Activation energies of 0.45 and 0.84 eV,deduced from the Arrhenius relation,were respectively found for the polyphosphate and the ultraphosphate.Taking into account the structural features of these materials we linked the origin of their electrical properties to the incorporation of atmospheric humidity.Thus,it was a proton conduction phenomenon which took place as a result of the establishment of hydrogen bonds as well as the reorganisation of water molecules already incorporated into these structures.Referring to the Grotthuss mechanism,a proton transfer model inside the polyphosphate's structure was suggested.Ines Hammas Karima Horchani-Naifer Mokhtar Férid 2010Journal of Rare Earths2010,28,3:3
3Crystal structure and infrared spectrum of thallium holmium polyphosphate, TlHo(PO_3)_4显示文摘Crystals of thallium-holmium polyphosphate TlHo(PO3)4 were grown by flux method technique and characterized by single crys- tal X-ray diffraction. Structure of TlHo(PO3)4 was solved for the first time, and it crystallized in the monoclinic P21/n space group with the following unit-cell dimensions: a=1.02225(3) nm, b=0.88536(2) nm, c=1.09541(4) nm, β=105.888(1)°, V=0.95354(5) nm3 and Z=4. The crystal structure was solved from 2174 independent reflections with final R1(F2)=0.0442 and Rw(F2)=0.0861 refined with 164 parameters. The atomic arrangement could be described as a long chain polyphosphate organization. Holmium atoms had eightfold coordination. The structure of TlHo(PO3)4 consisted of HoO8 polyhedra sharing oxygen atoms with phosphoric group PO4. Infrared spectrum was investigated at room temperature in the frequencies range, 350–4000 cm–1, showing some characteristic vibration bands of infinite chain structure of PO4 tetrahedra linked by bridging oxygen.Karima Horchani-Naifer Jaouher Amami Mokhtar Férid 2008Journal of Rare Earths2008,26,6:2
