, p. 489 - 493 (2001)
SnHPO4 was synthesized by precipitation and characterized by X-ray diffraction. The discharge curve of electrochemical cells using SnHPO4 as active cathode material and metallic lithium as anode showed a first reduction step at ca. 1.5 V. X-ray diffraction patterns of lithiated samples showed very weak bands ascribable to metallic tin. For the voltage values lower than 0.8 V the well-known Li-Sn alloy formation takes place. An intermediate step appears in the range from 1.2 to 0.8 V. The capacity retention is stabilized after 10 cycles at ca. 200 mAh/g.

The infrared and 119Sn-Moessbauer spectra of Sn2PO4Cl, SnPO4H, Sn2PO4(OH), and Sn3(PO4)2 have been recorded and interpreted in relation to known structural data.The results allow a wider insight into the bond properties of the phosphate groups as well as

Phosphate glasses are known to show proton conductivity, because they contain a significant amount of non-bridging oxygen and can contain water molecules. However, glasses prepared by the melting method have low-water content, resulting in very low-electrical conductivity (10?9–10?11 S cm). Hydrothermal treatment using an autoclave is useful to increase the proton content in glass obtained by the melting method and improve electrical conductivity. In this work, tin phosphate glasses are treated by hydrothermal conditions, and their electrical conductivity is investigated. After the hydrothermal treatment, the glasses change from transparent to white. The glasses are shown to be crystallized SnHPO4, Sn2(OH)PO4, and Sn2P2O7 by XRD. The formation of the crystals is occurred when the samples treated at 75 °C for 60 min, and the crystals are grown with increase of treatment time. The formation of these crystals causes the conductivity of the glasses to increase to 10?4 S cm when the glass is treated at 75 °C for 90 min.
Thermal Behavior of Tin Diphosphate Sn2P2O7

, p. 9 - 15 (2008/10/08)
Tin(II) diphosphate Sn2P2O7 in which tin(IV) is no more than 4% of the total tin is synthesized. The heating behavior of Sn2P2O7 in air, in vacuo (1.33 Pa), or under an argon atmosphere is studied using X-ray powder diffraction, differential thermal analysis (DTA), chemical analysis, crystal-optical analysis, IR spectroscopy, and M?ssbauer spectroscopy. Selected physicochemical properties of the α-Sn2P2O7, β-Sn2P2O7, Sn2P2O9, and SnP2O7 produced are determined.
