    摘要: A process for the preparation of lead molybdate pigments containing lead chromate, lead sulfate and lead molybdate, which comprises preparing the lead molybdate pigments by reacting an aqueous solution of a lead salt with an aqueous solution containing chromate, molybdate and sulfate salts or with an aqueous solution of each of said salts using 2 to 5 mol % of lead molybdate seed crystals, based on the total molar amount of lead chromate, lead sulfate and lead molybdate. The lead molybdate pigments so obtained are strong and are highly suitable for coloring organic materials of high molecular weight.
