Physical properties and main uses of Lead Oxide PbO
Lead Oxide PbO is a yellow or slightly reddish yellow powder or small flaky crystal, easy to change color when exposed to light; boiling point 1535°C; melting point 888°C, insoluble in water, insoluble in ethanol, soluble in nitric acid, acetic acid, hot lye; relative density (water=1)9.53.
The air can gradually absorb carbon dioxide. When heated to 300 ~ 500 ℃, it becomes lead tetroxide, and when the temperature is higher, it becomes Lead Oxide PbO. poisonous!
The main purpose
Lead Oxide PbO is used as pigment lead white, manufacturing lead soap, metallurgical cosolvent, paint drier, ceramic raw material, rubber vulcanization accelerator, pesticide, lead salt plastic stabilizer raw material, lead glass industry raw material, lead salt industry intermediate raw materials. A small amount is used in traditional Chinese medicine and in the battery industry, and in the manufacture of radiation-proof rubber products.
