Useage: it is used to make white lead powder, with oil is made into soap, in paint industry is used as lead drier, in plastic industry is used as stabilizer (i e PbO H2O 2PbSiO3 and 3PbO PbSO4 H2O) with great quantity is also used as theraw material for making optical glass, pottery and procelain; is also used to made radiation protection rubber, chrome pigment, and is used to make accumulator with a small amount.
