Application

Lead(II) chloride, a white crystalline powder, serves a critical purpose in the creation of perovskite materials. This compound, which naturally occurs as the mineral cotunnite, is integral as a precursor in the synthesis of perovskites due to its unique chemical properties. Given its composition of two chlorine atoms covalently bound to a central lead atom, Lead(II) chloride acts as a catalyst in various chemical reactions. Though slightly soluble in cold water and more soluble in hot water, it is this reactivity and its specific role in the reaction process that allows for the efficient synthesis of perovskites. These materials are pivotal in the development of advanced photovoltaic cells, improving their efficiency and stability. Lead(II) chloride's application in this domain underscores its importance in the forefront of material science innovation.

Other Experimental

Lead is derived from the decay of radon. /Inorganic lead/;Natural lead is a mixture of four stable isotopes: Pb-204 (1.4%), Pb-206 (25.2%), Pb-207 (21.7%) and Pb-208 (51.7%). Lead isotopes are the end-products of each of the three series of naturally occurring radioactive elements: Pb-206 for the uranium series, Pb-207 for the actinium series and Pb-208 for the thorium series. Forty-three other isotopes of lead, all of which are radioactive, are recognized.;Upon heating in air, readily forms basic chlorides.;Divalent lead has a strong affinity for inorganic ions containing oxygen (eg, carbonate) or sulfur (sulfide). Lead can also complex with electron rich ligands in many organic cmpd such as amino acids, proteins, and humic acid.
