Lead sulfide (PbS), also known as galena, is an inorganic compound combining lead and sulfur. It forms naturally as a tetrahedrite mineral and is subject to strict regulatory classifications due to its toxic byproducts when heated.
Employed in the production of pigments, paints, ceramic glazes, and lubricating oils, lead sulfide's use has been reconsidered due to lead's harmful effects. It serves as a primary source of lead and contributes to chemical conversion processes.
Lead sulfide exhibits a melting point of 1,114°C and a boiling point of 1,281°C. It is low in solubility, posing risks when thermally decomposed. Its black cubic crystals demonstrate semiconducting properties, being used in older semiconductor technologies.
Its sodium chloride-type crystal structure features octahedral coordination and has been explored in nanoparticles and quantum dots for potential solar cell applications.
Formation occurs when hydrogen sulfide or sulfide ions are introduced to lead ion solutions, creating a black precipitate. This reaction's high equilibrium constant facilitated its use in qualitative inorganic analysis.
Lead sulfide's sensitivity to infrared radiation makes it valuable in sensor elements, detecting radiation wavelengths from 1 to 2.5 µm at room temperature, with the range extending when cooled.
Lead(IV) sulfide (PbS2) emerges under high pressure and temperature conditions, presenting as a p-type semiconductor with potential thermoelectric material uses.
