출처Lead dichloride occurs in nature as the mineral cotunnite. The compound is used in making many basic chlorides, such as Pattison’s lead white, Turner’s Patent Yellow, and Verona Yellow, used as pigments. Also, it is used as a flux for galvanizing steel; as a flame retardant in nylon wire coatings; as a cathode for seawater batteries; to remove H2S and ozone from effluent gases; as a sterilization indicator; as a polymerization catalyst for alphaolefins; and as a co-catalyst in manufacturing acrylonitrile.

용도Lead(II) chloride is used in the synthesis of lead titanate and barium lead titanate ceramics; employed in the production of infrared transmitting glass and ornamental glass (aurene glass); useful as an electrode in geophysical applications and in solar cells. Analytical reagent, preparation of lead salts, as solder and flux. Pattinson's white lead, pigment in white paint, is the basic lead chloride.

일반 설명Prepared by reacting lead(II) oxide /acetate or carbonate with HCl. In crystalline PbCl2, each atom is coordinated by nine Cl atoms, six of which lie at the apices of a trigonal prism and the remaining three beyond the centers of the three prism faces. Each Cl is coordinated by four or five Pb atoms. Upon exposure to air it form basic chlorides such as PbCl2.Pb(OH)2.

Lead dichloride is precipitated by adding hydrochloric acid or any chloride salt solution to a cold solution of lead nitrate or other lead(II) salt: Pb2+ + 2Clˉ → PbCl2 Alternatively, it is prepared by treating lead monoxide or basic lead carbonate with hydrochloric acid and allowing the precipitate to settle..
