name and specification:
product name:another name is minium or optical mindan, scientific name lead tetroxide.
Molecular formula:
Molecular weight: 685.57
Property and usage:
Orange color powder, specific gravity is 9.1, decomposing the lead monoxide at 500oC, insoluble in water and alcohol, soluble in nitrate and hot alkali solution, part of it soluble in acetic acid. Becoming black lead sulfide easily under function of hydrogen sulfide which turning to white when exposed in the air and poisonous.
