<abstract xmlns="http://www.w3.org/1999/xhtml">The paper presents the results of a study on the corrosion behaviour of copper (EN CW004A) in five possible phase change materials (PCMs): magnesium nitrate hexahydrate pure and with an addition of Mg(OH)2 (0.5 wt. %) or Sr(OH)2 (0.5 wt. %) at 90 °C, calcium nitrate tetrahydrate at 50 °C and a mixture of magnesium nitrate hexahydrate and calcium nitrate tetrahydrate (1:1 mass ratio) at 72 °C. The corrosion rate of copper samples is low except for the use of Mg(NO3)2 · 6H2O with/without an addition of Mg(OH)2. The lowest corrosion rate was observed for the mixture Mg(NO3)2 · 6H2O—Ca(NO3)2 · 4H2O (1:1), and it was ca six times lower than that of pure magnesium nitrate hexahydrate.</abstract>
