Open Data Verified Data
yellow powder or granules. Relative density 9. 53; Melting point 885 ℃; Boiling point 1 470 ℃. When heated above 300 °c, it becomes lead trioxide, and then it becomes lead monoxide. Insoluble in water and ethanol, soluble in nitric acid, alkali, ammonium chloride; With glycerol hardening reaction. Under heating, lead monoxide is easily reduced to lead metal by hydrogen, carbon, carbon monoxide, etc.

lead (II) oxide, litharge, lead oxide - Introduction
Lead monoxide is an inorganic compound. It is in the form of yellow crystals or yellow powder. The following is an introduction to the properties, uses, production methods, and safety information of lead monoxide:
nature:
Chemical properties: Lead monoxide is soluble in concentrated hydrochloric acid or nitric acid, and reacts to form corresponding lead salts. It has a certain degree of corrosiveness.
Usage:
1. As a pigment: Lead monoxide has good covering and stability, and is widely used as a pigment, such as yellow lead powder or a component of various yellow pigments.
2. Preservatives: Lead monoxide is used as a preservative in coatings to prevent harmful substances from corroding the material.
3. Material additive: Lead monoxide can be used as an additive in glass, ceramics, and rubber products to enhance the hardness and stability of materials.
Method:
A common preparation method is to expose lead metal to air containing oxygen, allowing lead to react with oxygen to form lead monoxide.
Security information:
1. It is irritating to the skin, eyes, and respiratory tract. When operating, protective gloves, goggles, and masks should be worn to avoid contact and inhalation.
Long term exposure to high concentrations of lead monoxide may lead to lead poisoning, causing serious health problems such as gastrointestinal problems and neurological damage.
