- 論文の詳細を見る
Crystal structure of glassy K..,8(NH.)...2H2P0. is analysed using the Rietveldmethod in the temperature range from 20 K to 250 K. The lattice constant c shows ananomalous reduction between l20K and 150 K, where the NH. freezing occurs.Anomalous structure changes found at 100 K probably arise from the formation ofthe asymmetric hydrogen bonds without a long-range order.glass, K....(NH.)....H.P0., Rietveld analysis, X-ray powder diffraction
