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. It has been employed as a base material in this mixture to evaluate the storage and effective utilization of urban waste heat from emerged co-generation systems. Its crystals belong to the monoclinic crystal system.

Application

Magnesium nitrate hexahydrate may be used as a starting material for the synthesis of Mg-Al spinel precursors, required for the preparation of magnesium aluminate spinel (MgAl₂O₄) powder.
