摘要：
The results of a dilatometric study of the linear thermal expansion coefficient (LTEC) of polycrystalline samarium in the temperature range of 110-1050 K are presented. Temperature dependences have been obtained and reference tables of recommended values of thermal properties for the 110-1900 K interval of its solid and liquid states have been calculated. The nature of the LTEC change in the regions of phase transformations of the first and second kinds has been established. The critical indices of the linear thermal expansion coefficient at the Neel point have been determined.
