Product Description
Lead Oxide（red）
Bright orange-red powder or lumpy solid. Insoluble in water and alcohols, soluble in nitric acid (in the presence of hydrogen peroxide), glacial acetic acid, hot hydrochloric acid and hot lye.
Use
Red lead has been used as a pigment for primer paints for iron objects. Due to its toxicity, its use is being limited. It finds limited use in some amateur pyrotechnics as a delay charge and was used in the past in the manufacture of dragon's egg pyrotechnic stars.
Red lead is used as a curing agent in some polychloroprene rubber compounds. It is used in place of magnesium oxide to provide better water resistance properties.
Red lead was used for engineer's scraping, before being supplanted by engineer's blue. Although red lead still offers more accurate markings since it doesn't flow as readily as engineer's blue under pressure.
It is also used as an adulterating agent in turmeric powder.
