Key Words: Lead Oxide Red, Lead Oxide Yellow, Lead tetroxide, litharge, Orange lead, pigment red 105
Product Name: Lead Oxide Red/Lead tetroxide/pigment red 105, Lead Oxide Yellow,/litharge, Orange lead
red lead oxide(pigment red 105)
1. Name of Product and Standard:
Name of Product: Red lead, another name is bright lead, chemical identity is trilead teroxide.
Molecular Formula: Pb3O4
Molecular weight: 685.57
2. Characters and Uses:
Red Lead is a kind of fresh orange red powder, its specific density is 9.1, it starts to disintegrade into Lead Oxide at 500 , is insoluble in water and alcohol, soluble in nitric acid, partly soluble in glacial acetic acid, soluble in hot aqueous alkali. It changes into black Lead sulphide while meeting hydxgen sulphide, while put outdoor in the open air it changes into while Lead sulphate and it is poisonous.
Red Lead is mainly used to make Antirust Paint, Optical glass. Pottery glaze and Enamel, in electric industry is used to make piezofiles, in Chemical industry is used for weak oxidizer.
Yellow Lead(litharge)
1. Name of Product and Standard:
Names of Product: Yellow Lead, another name is litharge, Chemical identity is lead Monoxide.
Molecular formula: PbO
Molecular weight: 223.19
2. Characters and Uses:
Yellow Lead is a kind of yellow or yellowish brown powder, its specific density is 9.53, melting point is 888 , boiling point is 1470 . Heated to 300-500 , changes into Red Lead; With the temperature going on, changes into Yellow Lead again. It doesn't dissolve in water and alcohol, but dissolves in glacial acetic acid easily; it is poisonous while dissolving in nitric acid.
Yellow Lead is used to make white lead powder, with oil is made into soap, in paint industry is used as lead drier, in plastic industry is used as stabilizer (i e PbO H2O 2PbSiO3 and 3PbO PbSO4 H2O) with great quantity is also used as the raw material for making optical glass, pottery and procelain; is also used to made radiation protection rubber, chrome pigment, and is used to make accumulator with a small amount.
