CsLiB6O10 crystals with Cs deficit: structure and properties

Crystal growth of in a dry atmosphere and from a stoichiometric melt composition

“…It was reported that one of the sites where water molecules were incorporated was related to a Cs defect [7,8]. Thus, we suppose that generation of nonstoichiometric defects, including a Cs defect, may be decreased by growing the crystal from a stoichiometric melt.…”

“…When CLBO is grown from the stoichiometric melt, the growth temperature is just below the melting temperature, at about 850 3 C. The Czochralski (Cz) method is generally employed [7,8] because it is easy to achieve a temperature gradient around the solid-liquid interface. For the SS-TSSG method, the temperature gradient around the solid-liquid interface was about 0:1 3 C=mm.…”

Temperature- and moisture-dependency of CsLiB6O10. A new phase, β-CsLiB6O10

“…In addition, this compound shows ionic conductivity [2]. The crystal structure of CsLiB 6 O 10 was already described in literature [3][4][5]. Two structural models were suggested, one of them characterized by a split position for the Cs atom [5].…”

“…The crystal structure of CsLiB 6 O 10 was already described in literature [3][4][5]. Two structural models were suggested, one of them characterized by a split position for the Cs atom [5]. The study of the thermal behavior of the triborate structure is especially important because the crystals tend to crack under ambient conditions due to their high sensitivity to humidity.…”

“…IR absorption spectra of water in CsLiB 6 O 10 crystals have been measured between -186 and +25 °C [13]. Possible positions of the water molecules in the crystal were suggested [5,13,14].…”
