Litharge
Litharge, or lead monoxide, is an industrial lead oxide material used across selected chemical, glass, ceramic and manufacturing applications.
Lead Monoxide for Industrial Requirements
The existing S S International page describes Litharge as Lead Mono-Oxide (PbO), a yellowish or reddish, heavy, water-insoluble solid also referred to as lead monoxide, lead oxide, plumbous oxide and yellow oxide.
Commercial requirements can be reviewed against the requested specification, packing, quantity, destination and other mutually accepted supply terms.
Built Around the Buyerโs Requirement
Supply discussions are structured around the actual material specification and agreed commercial parameters.
Specification Review
Requested PbO content and physical properties can be reviewed against the applicable supplier specification.
Industrial Applications
Litharge is referenced for lead stabilisers, pottery, lead glass, paints, enamels and inks.
Trade Coordination
S S International supports requirement-based sourcing and buyer-seller commercial coordination.
