Low‐temperature change of lattice parameters in LiKB₄O₇ single crystals

Abstract

Structural investigations of LiKB4O7 crystals in the 13–290 K temperature range have been carried out by means of the high‐resolution powder diffraction technique applying synchrotron radiation. It is shown that the structural phase transitions are absent and all the linear thermal expansion coefficients αij are positive in the investigated temperature range.
