· JVASP-11780· MgCrO4

Magnesium chromate (MgCrO₄) is an inorganic ceramic compound combining magnesium and chromate ions, belonging to the broader family of metal chromates used in specialized applications. While not a commodity ceramic, it appears primarily in research and niche industrial contexts where its chemical properties—particularly corrosion inhibition and thermal stability—are leveraged. Engineers would consider this material for anti-corrosion coatings, pigments, and specialized refractory applications where chromate chemistry provides advantages over conventional alternatives, though regulatory restrictions on hexavalent chromium in some jurisdictions may affect its use.
