Abstract

Hydrated lead silicate suitable for a paint pigment is made by grinding a mixture of lead monoxide or hydroxide with silicic acid, preferably in a freshly precipitated gelatinous state, in water in the presence of an acid catalyst such as acetic, formic or nitric acid. The proportions are preferably such that the whole of the lead enters into combination and the final product may or may not contain a substantial amount of uncombined silica. The liquid is removed by centrifuging or filtering and the hydrated lead silicate dried, or if desired heated prior to use as a pigment, to about 250 DEG C. to remove some or all of the water of hydration. 0.5 per cent by weight of sulphuric acid, in addition to the acid catalyst may be added before, during or after grinding to prevent caking. Warming the mixture to 100 DEG C. after preliminary grinding accelerates the reaction.
