· JVASP-35319· PbS2

PbS2 (lead disulfide) is a chalcogenide ceramic compound belonging to the family of metal sulfides. While not widely commercialized as a bulk engineering material, lead disulfides are studied primarily in research contexts for optoelectronic and photovoltaic applications due to their narrow bandgap and potential for infrared detection and absorption. The material faces significant practical limitations for conventional structural applications, and its use is largely confined to specialized research environments and niche photodetector development rather than high-volume industrial manufacturing.
