General Manufacturing InformationPaint and Coating Manufacturing
Applications
UsesSodium bisulfate is used for pickling metals; bleaching leather; carbonizing wool; in carbonic acid baths, and manufacturing magnesia cements.
UsesMagnesium 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.
General DescriptionMagnesium 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.
