• Chemische Eigenschaften

  Lead(II) sulfide is a silvery to black crystalline powder.
  
  Lead(II) sulfide can be precipitated from a solution of lead (II) salt and hydrogen sulfide.
  Lead (II) sulfide has been used during many years as source of lead (Pb). The main method to obtain the lead is the smelting of PbS and then, the lead (II) oxide obtained is reduced to Pb and carbon monoxide:
  2 PbS + 3 O2 → 2 PbO + 2 SO2
  PbO + C → Pb + CO
  Moreover, lead (II) sulfide is used as semiconductor and photoconductor due its chemical proprieties. It is also used as black pigment. In recent years, it has been used in to obtain nanoparticles to use in electronic or electric devices.

• Verwenden

  Lead(II) sulfide is used as a semiconductor. Used in electronic devices and Infrared sensor.

• Verwenden

  The size for our lead sulfide (PbS) quantum dots (QDs) varies between 2.5 to 8 nm and depending upon this, these QDs emit between 900-1600 nm. Our PbS QDs possess high quantum yield, sharp emission and exhibit narrow fluorescence band (full width at half maximum <100 nm), which make them suitable as light absorber or IR emitter in applications in solar cells, photodetectors and infrared light emitting diodes (LEDs).

• Verwenden

  Glazing earthenware.

• Definition

  galena: A mineral form of lead(II)sulphide, PbS, crystallizing in thecubic system; the chief ore of lead. Itusually occurs as grey metallic cubes,frequently in association with silver,arsenic, copper, zinc, and antimony.Important deposits occur in Australia(at Broken Hill), Germany, the USA(especially in Missouri, Kansas, andOklahoma), and the UK.

• Reaktivität anzeigen

  The reaction between iodine monochloride and any of the following is vigorous: cadmium sulfide, LEAD(II) SULFIDE, silver sulfide, or zinc sulfide [Mellor 2, Supp. 1:502. 1956].

• Health Hazard

  INHALATION OR INGESTION: Abdominal pain, loss of appetite, weight loss, constipation, apathy or irritability, vomiting, fatigue, headache, weakness metallic taste and muscle incoordination. Lead line on gums. EYES: Irritation. May cause corneal destruction. SKIN: Pain and severe burns.

• Brandgefahr

  Behavior in Fire: At fire temperatures emits highly toxic and irritating sulfur oxides.

• mögliche Exposition

  Lead sulfide is used in ceramics, infrared radiation detectors, and semiconductors.

• Erste Hilfe

  If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention.Note to physician: whole blood lead levels, circulatingplasma/erythrocyte lead concentration ratio, urine ALA,and erythrocyte protoporphyrin fluorescent microscopy mayall be useful in monitoring or assessing lead exposure.Chelating agents, such as edetate disodium calcium (CaEDTA) and penicillamine (not penicillin) are generally useful in the therapy of acute lead intoxication.Antidotes and special procedures for lead: Persons with significant lead poisoning are sometimes treated with CaEDTA while hospitalized. This “chelating” drug causes arush of lead from the body organs into the blood and kidneys, and thus has its own hazards, and must be administered only by highly experienced medical personnel undercontrolled conditions and careful observation. Ca EDTA orsimilar drugs should never be used to prevent poisoningwhile exposure continues or without strict exposure control,as severe kidney damage can result.Note to physician: For severe poisoning BAL [British AntiLewisite, dimercaprol, dithiopropanol (C3H8OS2)] has beenused to treat toxic symptoms of certain heavy metals poisoning. In the case of lead poisoning it may have SOMEvalue. Although BAL is reported to have a large margin ofsafety, caution must be exercised, because toxic effects maybe caused by excessive dosage. Most can be prevented bypremedication with 1-ephedrine sulfate (CAS: 134-72-5).

• Lager

  Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Lead sulfide must be stored to avoid contact withoxidizers (such as perchlorates, peroxides, permanganates,chlorates, and nitrates) and chemically active metals (suchas potassium, sodium, magnesium, and zinc), since violentreactions occur. Store in tightly closed containers in a cool,well-ventilated area away from moisture and acids. Lead isregulated by an OSHA Standard 1910.1025. All requirements of the standard must be followed. A regulated,marked area should be established where this chemical ishandled, used, or stored in compliance with OSHAStandard 1910.1045.

  UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required. UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1- Poisonous materials, Technical Name Required.

• Structure and conformation

  The space lattice of PbS belongs to the cubic system, and its rock salt structure has a lattice constant of a=0.592 nm and Pb-S=0.296 nm.

• Inkompatibilitäten

  Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, and iodine monochloride. Sulfides react with acids to produce toxic and flammable vapors of hydrogen sulfide.
