Qingdao Yosion Labtech Co., Ltd.  

Product Name: Lead Acid Component Yellow/Red Pbo Litharge for Ceramics, Glass, Rubber Quality: First Class Kind: Alkaline Oxide Grade Standard: Industrial Grade Classification: Lead Oxide Formula: Pbo Trademark: Yosion Transport Package: Export Packing Specification: yellow/red Origin: China Product Description Yellow Lead is a kind of yellow or yellowish brown powder, its specific density is 9.53 g/cm3, melting point is 888°C, boiling point is 1470°C. Heated to 300-500°C, 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, with great quantity is also used as the raw material for making optical glass, pottery and porcelain; is also used to made radiation protection rubber, chrome pigment, and is used to make accumulator with a small amount.Red Lead is a kind of fresh orange red powder, its specific density is 9.1 g/cm3, it starts to disintegrate into Lead Oxide at 500°C , 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 hydrogen 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 pressure cell, in Chemical industry is used for weak oxidizer.ITEMSConTENT %Lead Monoxide99.55SiO20.001CaO0.0002Aluminum Oxide0.0002Fe0.0003Zn0.0001Insoluble matter0.005As0.0002Bismuth0.0002metallics0.005Silver0.0042Gold<1Size200mesh
