Sodium magnesium sulfate

Sodium magnesium sulfate is a double sulfate of sodium and magnesium. There are a number of different stoichiometries and degrees of hydration with different crystal structures, and many are minerals. Members include:

  • Blödite or bloedite: sodium magnesium sulfate tetrahydrate Na2Mg(SO4)2•4H2O[1]
  • Disodium magnesium disulfate decahydrate Na2Mg(SO4)2•10H2O[2]
  • Disodium magnesium disulfate hexadecahydrate Na2Mg(SO4)2•16H2O[3]
  • Na2SО4·MgSO4·2.5H2O[4]
  • Konyaite Na2Mg(SO4)2•5H2O[5]
  • Löweite Na12Mg7(SO4)13•15H2O.[6][7]
  • Vanthoffite Na6Mg(SO4)4
  • Na2Mg2(SO4)3 langbeinite form stable from 569.2 to 624.7°C[8]
  • Na2Mg2(SO4)3 quenched monoclinic form[8]
  • Na2Mg3(SO4)4 orthorhombic form[8]
  • Na2Mg(SO4)2 triclinic form[8]
