· JVASP-12232· HgMoO4

Mercury molybdate (HgMoO4) is an inorganic ceramic compound combining mercury and molybdenum oxide in a binary metal oxide system. This material is primarily of research and specialized industrial interest rather than a high-volume engineering commodity, with applications in optical materials, pigmentation, and specialized chemical sensing contexts. Its notable characteristics—including its high density and crystal structure—make it relevant for niche optoelectronic and photonic applications where mercury-containing ceramics offer advantages in refractive index matching or selective wavelength response.
