ceramic

· JVASP-12581· MgH2SeO5

MgH₂SeO₅ is an inorganic ceramic compound combining magnesium hydride with selenate chemistry, representing an experimental or research-phase material rather than an established commercial product. This compound belongs to the family of magnesium-based ceramics and hydride-containing materials, which are of interest in hydrogen storage research, advanced refractory applications, and solid-state chemistry. The material's technical relevance would primarily lie in niche applications requiring specific combinations of magnesium chemistry, hydride functionality, and ceramic stability—areas where conventional oxides or silicates are insufficient.
