· JVASP-45292· HgB4O7

HgB4O7 is a mercury borate ceramic compound belonging to the borate oxide family of advanced ceramics. This material is primarily of research and specialized industrial interest, with applications in optical, thermal, and electronic domains where mercury-containing oxides offer unique properties such as high refractive index or specific thermal characteristics. The material represents the broader class of heavy metal borates explored for niche engineering applications where their distinctive properties cannot be easily replicated by more common ceramic alternatives.
