The thermal behavior of Na3H(SO4)2 is studied in the temperature range –180...220°C in a pre-vacuum. At 180°C, the compound decomposed into a mixture of phases: Na2SO4 (Cmcm), Na2SO4 (P63/mmc), Na2SO4 (Fddd), and Na2S2O7. The maximal thermal expansion was observed near the α33 axis. The anisotropy of thermal expansion sharply decreased together with the increase in temperature.
