황화 납 C화학적 특성, 용도, 생산
화학적 성질
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.
용도
Lead(II) sulfide is used as a semiconductor. Used in electronic devices and Infrared sensor.정의
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.반응 프로필
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].건강위험
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.화재위험
Behavior in Fire: At fire temperatures emits highly toxic and irritating sulfur oxides.잠재적 노출
Lead sulfide is used in ceramics, infrared radiation detectors, and semiconductors.운송 방법
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.비 호환성
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.황화 납 준비 용품 및 원자재
