ceramic

· JVASP-12161· HgPSe3

HgPSe3 is a layered ternary ceramic compound combining mercury, phosphorus, and selenium in a two-dimensional crystal structure. This material is primarily of research interest rather than established industrial use, belonging to a family of van der Waals solids that exhibit weak interlayer bonding—a property that makes such compounds candidates for mechanical exfoliation into thin films and heterostructure engineering. The material's layered nature and mixed-anion composition position it within emerging research on optoelectronic semiconductors, topological materials, and flexible electronics, though practical applications remain largely experimental.
