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.

Although MgO-Al2 O3 is well known as having a spinel structure, the inversion of which occurs by exchange of the trivalent (Al3+ ) and divalent (Mg2+ ) cations, little analytical study of the degree of inversion has been carried out.

The development of carbon dioxide (CO2) sorbents that can operate at elevated temperatures is significant for the advancement of pre-combustion capture technologies. Recently, promoter-based systems composed of alkali/alkaline earth metal nitrates and/or carbonates have been considered as next-generation solid sorbents
