La description
red lead oxide(pigment red **5) 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: **5.*7 2. Characters and Uses: Red Lead is a kind of fresh
organge red powder, its specific density is 9.1, it starts to
disintegrade into Lead Oxide at **0 , 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: **3.*9 2.
Characters and Uses: Yellow Lead is a kind of yellow or yellowish
brown powder, its specific density is 9.*3, melting point is **8 ,
boiling point is ***0 . Heated to ******0 , 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. Meanwhile, we also can supply
molybdate red molybdate orange zic chrome yellow Chrome yellow
Organic chrome yellow Chrome green Titanium dioxide rutile/anatase
Iron oxide red/yellow/orange/black/orange/green
