lead processingChromatesLead chromates—yellow, orange, and red—have significant application as pigments. The standard chromate, PbCrO4, is made by precipitation from solutions of lead acetate or lead nitrate to which potassium or sodium bichromate has been added. Gradations of colour are obtained by varying the types of…
