• Lead Sulfides an overview | ScienceDirect Topics

    In Handbook of Stable Isotope Analytical Techniques, 2009. Reduction with Fe Metal Powder. Thode (1953) described the reduction of sulfate by mixing it with excess Fe powder in a porcelain crucible and heating over a burner for 2 h. The slag was treated with HCl and the released H 2 S was trapped in a lead sulfide solution, precipitating PbS. The PbS was, after …

  • Zinc Sulfide

    Unusual Fire Explosion Hazards: Zinc sulfide decomposes at temperatures greater than 400 o C in air and/or in oxidizing atmospheres. Zinc sulfide produces zinc and sulfur fumes at temperatures greater than 900 o C in inert atmospheres. Contact with strong acids may liberate hydrogen sulfide which may form explosive mixtures in air.
