Product Description
Descriptions of the Dibasic Lead PhosphiteMolecular Formula:2PbO·PbHPO3·H2OProperties:Dibasic Lead Phosphite is white or light yellow powder. It has sweetness while it is toxic. The density is 6.1 and the refractive index is 2.25. Dibasic Lead Phosphite will become grey black when the temperature is about 200 and turn yellow with the temperature around 450.
Dibasic lead phosphite can not dissolve in water and organic solvents but it can dissolve in hydrochloride and nitric acid. The weatherability, heat resistance, and electric insulation are all excellent.
More than that, It has oxidation resistance and can shield ultraviolet radiation.Quality Indicators: (in line with the HG2339-92) Item Best quality First quality Qualified Product
