white, monoclinic, crystal(s) powder(s) [CRC10]
Lead monosilicate (lead pyrosilicate), 1.5PbO· SiO2, is a light yellow trigonal crystalline powder, insoluble in water. Its composition, by weight, is 85% PbO and 15% SiO2. Lead monosilicate is commercially available as granular, <1.68 mm (10 mesh), and ground, 97% through 44 μm (325 mesh). It provides the most economical method of introducing lead into a ceramic glaze. It is also used as a source of PbO in the glass industry.
LEAD MONOSILICATE is used as rust-inhibiting pigments. When added to polymers, they can be used as wear-resistant materials. They can also be used as heat stabilizers for polymers, and are found in the manufacture of optical glass, cathode ray tubes, optical fibers, everyday utensils, and for low-melting-point welding.
