Basic lead phosphite
Chemical compound
Basic lead phosphite is an inorganic compound with the proposed composition Pb3O(OH)2(HPO3).[1] The compound contains the phosphite anion, which provides the reducing properties associated with the application of this material.
It is widely used as a stabilizer for chlorine-containing polymers, especially polyvinylchloride.[2] Other lead phosphites are known, including normal lead phosphite, PbHPO3, although the basic salt is especially effective.[3]
