Red Lead- Understanding its different uses Red lead also known as minium or triplumbic tetroxide is an orange and red crystalline which is widely used in the manufacturing of lead glass, storage batteries and rust proof primer paints. Chemically, red lead is 2 PbO.PbO2 or Pb3O4 that forms insoluble iron (III) plumbates and insoluble iron (II) plumbates, which is the basis of anti-corrosive properties. Minium is virtually insoluble in alcohol and water. However, it is soluble in hydrochloric acid present in the stomach and hence, very harmful for health. Besides this, this lead oxide also leads pollution and several health issues. This is why this use of this lead oxide is very limited. Read on to understand the use and benefits of Red Lead. 1. Red Lead is most often used as a pigment for primer paints. Earlier, it has been used in combination with linseed oil as a thick anti-corrosive paint. Lead oxide forms Iron (II) an Iron (III) plumblets, which is the basis of anticorrosive properties. 2. Minium is also used for plumbing with the combination of linen fibers. 3. Minium is also used in the manufacturing of crystal glass, which is also known as lead glass. 4. This metal oxide is also utilized as a curing agent in some polychloroprene rubber compounds. It is also used as the best alternative of magnesium oxide to provide excellent water resistance properties. 5. Minium is also widely used for the engineer’s scraping. 6. Red lead is also used in traditional Chinese medicines for the treatment of ulcerations and ringworms. 7. And much more‌.. As Red lead causes pollution and very harmful for human health, the production of red lead products is very limited. Moreover, a company need approval from legal and government bodies for the production of lead products. Considering this the main reason why most of the companies are turning towards meta recycling firms for the production of lead products. The metal recycling companies are certified
