Quick Summary

Lead silicates are a versatile group of chemical compounds derived from lead and silica. They are created by reacting lead monoxide or a lead salt with silica or a silicate. Commercially, three main types are available: lead monosilicate, lead bisilicate, and tribasic lead silicate.12

These compounds are extensively used in the ceramics industry for glazes and ceramic bodies. They are also utilized in glass manufacturing, dry-process enamels, and frit batches. Additionally, lead silicates can serve as white pigments for exterior paints and are used in compounding rubber.12

Silicates
Lead silicates are considered to be the most versatile of lead chemical compounds in the ceramics industry. Three types are available commercially: lead monosilicate (PbO·0.67SiO₂), lead bisilicate (PbO·0.03Α1₂O₃·1.95SiO₂), and tribasic lead silicate (PbO·0.33SiO₂). The silicates are used extensively in finely divided form for glazes…
