Litharge preparation
The kind of lead in lead glass is normally PbO, and PbO is used extensively in making glass. Depending on the glass, the benefit of using PbO in glass can be one or more of increasing the refractive index of the glass, decreasing the viscosity of the glass, increasing the electrical resistivity of the glass, and increasing the ability of the glass to absorb X-rays. Adding PbO to industrial ceramics (as well as glass) makes the materials more magnetically and electrically inert (by raisi… WebLitharge is a special type of lead oxide. Highly pure lead oxide is used in the determination of gold and silver by fire assay. Its color is typicall a reddish-orange and chemical formula is PbO, easy to change color when exposed to light. Melting point (℃): 888~890 Boiling point (℃): 1472 (decomposition) Relative density (water = 1): 9.53
