MgSO4

Magnesium sulfate (MgSO₄) is an inorganic salt ceramic compound commonly known as Epsom salt in its heptahydrate form. In engineering applications, it serves primarily as a raw material for chemical production, a desiccant, and a filler in composite systems, with industrial relevance in construction, pharmaceutical manufacturing, and laboratory environments. Engineers select MgSO₄ for applications requiring mild alkalinity buffering, moisture absorption, or as a precursor phase in magnesium-based ceramic composites, though its solubility in water limits use in fully load-bearing structural roles compared to oxide ceramics like alumina or zirconia.
