The thermal behavior of antiferromagnets FeBO₃ and Fe₃BO₆ is investigated according to the low-temperature powder X-ray diffraction data. Unit cell parameters were refined by the Rietveld method. The coefficients of thermal expansion are calculated. The interrelation between the expansion and crystal structure is described.
