Product Application of Lead Monoxide CAS#1317-36-8
Lead monoxide is widely used in the production of PVC plastic stabilizers and serves as an important raw material for the manufacture of various lead salts. In the paint industry, it reacts with oils to form lead soaps that function as effective paint driers. It is also utilized in the production of high-refractive-index optical glass, ceramic enamels, and flat abrasives used for precision machine tools. In addition, it is applied as a medical raw material, a rubber colorant, and is commonly used in battery plate manufacturing as well as petroleum refining processes.
