Variation of unit-cell size of indium nitride with temperature has been studied in Refs. [1-3]. The low-temperature range has been only partially explored up to now. In the present study, the lattice parameters for indium nitride were determined using X-ray powder diffraction at a synchrotron radiation source (beamline B2, Hasylab/DESY, Hamburg) in the temperature range from 22 K up to 310 K. An image-plate detector was applied for data collection. The wavelength was calibrated using internal diamond standard, according to the method described in Ref. [4]. The lattice parameters a and c behave in a similar way: they are virtually constant below about 130 K. In the range 200 to 300 K the variation is close to a linear one. Discussion of the results will involve the earlier studies of thermal expansion of indium nitride.
