Pb(NO3)2 (Plumbous Nitrate) 4. The mineral clausthalite is a naturally occurring lead selenide. Once electrical potential is applied, impure lead at the anode dissolves and plates onto the cathode, leaving the majority of the impurities in solution. [104], Lead is classified as a chalcophile under the Goldschmidt classification, meaning it is generally found combined with sulfur. Provied information about LEAD SELENIDE(Molecular Formula: PbSe, CAS Registry Number:12069-00-0 ) ,Boiling Point,Melting Point,Flash Point,Density,NMR Specturm,Molecular Structure,Risk Codes,Synthesis Route at guidechem [255] Early childhood exposure has been linked with an increased risk of sleep disturbances and excessive daytime drowsiness in later childhood. An even number of either protons or neutrons generally increases the nuclear stability of isotopes, compared to isotopes with odd numbers. [280], Analytical methods for the determination of lead in the environment include spectrophotometry, X-ray fluorescence, atomic spectroscopy and electrochemical methods. Cadmium selenide is an inorganic compound with the formula Cd Se. Lead's toxicity has led to its phasing out for some uses. The effects of chronic ingestion of lead, including mental disorders, were also studied in the 19th century. [260] Seawater products can contain lead if affected by nearby industrial waters. On capturing another neutron, lead-208 becomes lead-209, which quickly decays into bismuth-209. … Selanylidenecadmium. [v] Old houses may still contain lead paint. [129] Lead was used to make sling bullets from the 5th century BC. High purity, submicron and nanopowder forms may be considered. Because of technological limitations associated to this method of processing, nowadays the biggest CBD PbSe detector format commercialized is a linear array of 1x256 elements. Name. [225] Its use in solder for electronics is also being phased out by some countries to reduce the amount of environmentally hazardous waste. Formula: PbSe2. [s] People who work in battery production plants may be exposed to lead dust and inhale it. Hg 2 2+ Mercury. [186] The process is similar to that of primary production in either a blast furnace or a rotary furnace, with the essential difference being the greater variability of yields: blast furnaces produce hard lead (10% antimony) while reverberatory and rotary kiln furnaces produced semisoft lead (3–4% antimony). Gaseous by-product of the coking process, containing. N 3 − Azide. [92] The amount of lead in the universe is slowly increasing[93] as most heavier atoms (all of which are unstable) gradually decay to lead. [193][194] De-silvered lead is freed of bismuth by the Betterton–Kroll process, treating it with metallic calcium and magnesium. Lead(III) may be obtained, as an intermediate between lead(II) and lead(IV), in larger organolead complexes; this oxidation state is not stable, as both the lead(III) ion and the larger complexes containing it are radicals. Element % In: 59.25: Se: 40.75: Isotope pattern for InSe. [181] As was the case during European industrialization, lead has had a negative effect on health in China. In the second half of the 18th century, Britain, and later continental Europe and the United States, experienced the Industrial Revolution. [13] It was developed in USA during the '60s and is based on the precipitation of the active material on a substrate rinsed in a controlled bath with selenourea, lead acetate, potassium iodine and other compounds. "Lead: properties, history, and applications" (PDF). The association of lead and tin can be seen in other languages: the word olovo in Czech translates to "lead", but in Russian, its cognate олово (olovo) means "tin". [82] In such anions, each atom is at a polyhedral vertex and contributes two electrons to each covalent bond along an edge from their sp3 hybrid orbitals, the other two being an external lone pair. [11], As a sensitive material to the infrared radiation, PbSe has unique and outstanding characteristics: it can detect IR radiation of wavelengths from 1.5 to 5.2 μm (mid-wave infrared window, abbreviated MWIR – in some special conditions it is possible to extend its response beyond 6 μm), it has a high detectivity at room temperature (uncooled performance), and due to its quantum nature, it also presents a very fast response, which makes this material an excellent candidate as detector of low cost high speed infrared imagers.[12]. NOTE: ALL NUMBERS IN FORMULAS SHOULD BE WRITTEN AS SUBSCRIPTS. An ionic formula, like \(\ce{NaCl}\), is an empirical formula. [152][158] Lead was a key material in parts of the printing press, and lead dust was commonly inhaled by print workers, causing lead poisoning. [16], Except where otherwise noted, data are given for materials in their, Methods to manufacture PbSe infrared detectors, "High-temperature thermoelectric performance of heavily doped PbSe", "Study of the Thermoelectric Properties of Lead Selenide Doped with Boron, Gallium, Indium, or Thallium", National Pollutant Inventory - Lead and Lead Compounds Fact Sheet, https://en.wikipedia.org/w/index.php?title=Lead_selenide&oldid=996499833, Articles containing unverified chemical infoboxes, Articles with unsourced statements from February 2007, Creative Commons Attribution-ShareAlike License, This page was last edited on 26 December 2020, at 23:55.
