General description

Magnesium nitrate hexahydrate is a hydrated magnesium salt. A mixture of magnesium nitrate hexahydrate and magnesium chloride hexahydrate has been reported as a potential phase change material (PCM) for the storage of latent thermal energy.

Application

Magnesium nitrate hexahydrate can be used:
  • In the synthesis of magnesium oxide (MgO) nanopowder by thermal plasma method.
  • As a starting material in the synthesis of magnesium nitrate – alumina composite [(1-x) Mg (NO3)2 – xAl2O3] via sol-gel method.
  • As a starting material for the synthesis of Mg-Al spinel precursors, required for the preparation of magnesium aluminate spinel (MgAl2O4) powder.
