Abstract

Abstract Structural investigation of Li 2B 4O 7 in the 10–290 K temperature range has been carried out by means of high-resolution powder diffraction technique applying synchrotron radiation. The obtained results show high thermal stability of tetraborate groups in the 10–290 K temperature range. The planar BO 3 triangles somewhat enlarge at heating, while the BO 4 tetrahedra compress excessively at heating from 10 to 290 K. In the 10–290 K temperature range maximal changes were observed for structural parameters of Li atoms, while the parameters of O atoms show minimal temperature variations.
