Description

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.

Safety Information

• Storage Class Code: 13 - Non Combustible Solids
