· JVASP-9548· Mg2Bi2O5

Mg₂Bi₂O₅ is an inorganic oxide ceramic compound composed of magnesium and bismuth oxides, belonging to the family of mixed-metal oxides with potential functional ceramic applications. This material is primarily of research interest rather than established in high-volume production, with investigation focused on its electrical, thermal, and structural properties for specialized ceramic applications. The bismuth-containing oxide system is explored for potential use in electroceramics, thermal barrier systems, and radiation-shielding applications where its dense structure and multi-component composition offer advantages over simpler single-oxide ceramics.
