Litharge, which is Lead Mono-Oxide (PbO) is a yellowish or reddish, odorless, heavy, earthy, water-insoluble, solid, PbO, used chiefly in the manufacture of Lead Stabilizers (Lead Steareates), pottery, Lead glass, paints, enamels, and inks.Litharge is also called Lead Monoxide, Lead Oxide, Plumbous Oxide & Yellow oxide.Other uses of Litharge are as an intermediate in a variety of industries like lubricants and greases, insecticides, inorganic pigments, Lead soaps, petroleum refining, rubber and PVC etc.Our manufacturing Plant for Litharge has a Barton plant as the common first step. The required input is refined Lead ingots of minimum 99.98% purity. The Barton plant output is routed to the Litharge furnace with their respective equipment complement, which comprises of the Litharge furnace, grinder, cyclone and bag-house arrangements, ending in a mixer / silo, Pulverizer & packing section.
