What is Lead monoxide?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Lead monoxide which has developed particularly rapidly in recent years. Do you know about Lead monoxide?


The official answer:Lead oxide is an inorganic substance with the chemical formula PbO, a yellow tetragonal crystalline powder. When heated to 300-450°C it changes to lead trioxide, and then to lead monoxide when the temperature continues to rise. Insoluble in water and ethanol, soluble in acetone, nitric acid, liquid alkali and ammonium chloride. Can react with glycerol to harden. Toxic.

What’s the application of Lead monoxide?

Used as an analytical reagent, flux for silicates, also for the precipitation of amino acids.
