Basic Salts Sorel Cements

Mixtures of glycerin and liiharge (lead oxide or PbO) are used as adhesives in the repair of tubs and sinks, pipe valves, glass, stoneware, and common gas conduits. A mixture of one part slightly diluted glycerin with two to three parts of lead oxide requires approximately 1 day to form a crystalline compound. The resulting cement resists weak acids and nitric acid but reacts with sulfuric acid. These materials have also been used as ceramic seals in potting electronic equipment. [Pg.157]
