- W1968730257 abstract "The high-temperature transformation of ${mathrm{CsH}}_{2}{mathrm{PO}}_{4}$ was studied by means of impedance spectroscopy, differential thermal analysis, and thermogravimetric methods. The dielectric constant showed a high-temperature anomaly around ${T}_{p}=230ifmmode^circelsetextdegreefi{}mathrm{C}.$ The thermal transformation which appears around ${T}_{p}=230ifmmode^circelsetextdegreefi{}mathrm{C}$ is endothermic in addition to showing weight loss. Our results show evidence that the high-temperature transformation of ${mathrm{CsH}}_{2}{mathrm{PO}}_{4}$ near ${T}_{p}$ is not a structural phase transition, but an onset of thermal decomposition of ${mathrm{CsH}}_{2}{mathrm{PO}}_{4}$ into ${mathrm{Cs}}_{n}{mathrm{H}}_{2}{mathrm{P}}_{n}{mathrm{O}}_{3n+1}$ [probably $nensuremath{gg}1,$ $({mathrm{CsPO}}_{3}{)}_{n}]$ at reaction sites at the surface of the crystal. From complex ac impedance spectra, we observed impedance consisting of two regions for measuring frequency: the low-frequency region may be due to the formation and migration of ${mathrm{H}}_{2}mathrm{O}$ molecules at the surface while the conduction mechanism of the high-frequency region seems to be Cole-Cole type and may be due to the proton migration in the bulk. Our results support that the phase of ${mathrm{CsH}}_{2}{mathrm{PO}}_{4}$ above ${T}_{p}$ is not a superionic conductor phase caused by a structural transition $(mathrm{monoclinic}ensuremath{rightarrow}mathrm{cubic})$ but rather a polymeric state caused by partial thermal decomposition. The possible origin of proton conduction for ${mathrm{CsH}}_{2}{mathrm{PO}}_{4}$ is considered to be the partial thermal decomposition of the crystal surface because the polymeric transition tends to increase breaking and reforming of the hydrogen bond at the surface." @default.
