N2  - The temperature dependence of the structural parameters of orthorhombic suicide GdSi: was studied by the in situ powder x-ray diffraction method, A structural change from orthorhombic to α-ThSi2-type tetragonal was found at around 818 K. The change in structure with temperature is continuous and reversible without a discontinuous change in volume, The thermal expansion coefficient was calculated from the refined cell parameters. The compound began to react with the residual oxygen in the argon environment and form oxide above 973 K.<p /> <p>Language: en</p>
