What is LEAD MONOSILICATE?
Chemical properties
white, monoclinic, crystal(s) powder(s) [CRC10]
Chemical properties
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.
