· JVASP-35177· MgS2O7

MgS2O7 is an inorganic ceramic compound based on magnesium and sulfate chemistry, belonging to the family of magnesium sulfate derivatives. This material is primarily of research and specialized industrial interest, used in applications requiring thermal stability, chemical resistance, and moderate mechanical stiffness where magnesium-based ceramics offer advantages over traditional oxides. Its sulfate chemistry makes it relevant to refractory applications, high-temperature insulation, and potentially in specialized cement or binding systems where magnesium compounds provide durability in corrosive or thermally demanding environments.
