Product Description of Lead Monoxide CAS#1317-36-8
Lead monoxide belongs to the family of inorganic chemicals and carries the formula PbO. It presents as yellow crystalline powder. It cannot dissolve in water or ethanol, yet dissolves readily in nitric acid, acetic acid and hot alkaline liquids. This lead compound serves broadly as color pigment and metallurgical flux, and also works as a drying agent for paints. Besides these, it acts as a vulcanization promoter for rubber and acts as raw material for pesticide manufacturing, along with many other industrial usages.

Product Application of Lead Monoxide CAS#1317-36-8
Lead monoxide is extensively deployed for making PVC stabilizers and acts as a core starting material to synthesize a range of lead salt products. For coating manufacturing, it undergoes reactions with fatty oils to yield lead soaps, which deliver reliable drying performance for paints. It further supports the fabrication of high-refraction optical glass, ceramic enamel coatings and planar polishing abrasives tailored to precision machinery. Beyond these fields, it can be applied for pharmaceutical preparation, rubber tinting, and sees regular use in battery electrode sheet production and oil refining operations.
