· JVASP-10995· MgSeO4

Magnesium selenate (MgSeO₄) is an inorganic ceramic compound combining magnesium and selenate ions, belonging to the sulfate/selenate mineral family. While not widely deployed in mainstream engineering, this material is primarily of research and specialized interest for applications requiring selenate-containing phases, such as in nuclear waste immobilization, geological sequestration studies, and fundamental materials research on ionic ceramics. Engineers would consider MgSeO₄ in niche contexts where selenate chemistry or magnesium-based host matrices are critical, though more established alternatives typically dominate industrial applications.
