895℃ 這個是總結(jié)文獻來的 The thermal decomposition of eleven (II) sulphates has been studied by a combination of thermogravimetric and differential thermal analysis. The relative decomposition temperatures are: MnSO4 755, FeSO4 537, CoSO4 708, NiSO4 675, CuSO4 598, ZnSO4 646, CdSO4 816, PbSO4 803, MgSO4 895, CaSO4 1149, and SrSO4 1374°C. Factors possibly influencing thermal stability of such salts are discussed, with special consideration of the effects of the metal's electronegativity and polarizing power on the condition of the anion. |

在900℃以下時很穩(wěn)定,加熱至1127℃時分解放出SO2。 https://www.basechem.org/chemical/21545 |
