Abstract
AbstractAn overview of the use of molybdenum for producing pigmentary materials is provided. Pigments are introduced in terms of their basic properties, and their relationship with dyestuffs is explained. The characteristics of a pigment are a function not only of its chemical structure, but also of its physical form and especially of its particlesize distribution. Pigment particles may vary in size from about 0.05 to 1 micron, the optimum size being related to the properties required for a particular application.The three major areas of molybdenum usage are identified as molybdate orange, basic dye pigments and anticorrosive pigments. Each of these is described in terms of manufacture, chemical and physical structure, economic position within the pigment field, marketing potential and applications. Molybdate orange accounts for by far the largest portion of pigmentary molybdenum usage. This relatively low cost, yet remarkably versatile pigment is a solid solution of lead molybdate, lead sulphate and lead...
