Hartmut Endriss 2.1 Introduction Bismuth vanadate pigments are a relatively new pigment class that has gained steadily in importance over the last two decades. The pigments exhibit brilliant greenish-yellow to reddish-yellow shades, with compositions ranging from BiVO4 (CAS No. 14059-33-7, EINECS No. 237-898-0) to the mixed pigment 4BiVO4 x 3Bi2MoO6. They appear in the Colour […]

This leads us to consider challenges for new high performance pigments, which can be designated as Three Essential Es: Effectiveness = Technical performance Economy = Benefits for the customer Ecology = Environmental and toxicological safety Better effectiveness could include higher tinting strength, greater ease of disper­sion, better fineness of grind, higher saturation, and so on. […]

Bearing in mind the limitation in the color of inorganic pigments, one has to be surprised at the numbers of new compounds introduced with good pigment per­formance. More and more, specialized physical effects appear to dominate over variation in chemical composition. In Table 1.1, for example, we must point out that mica-based effect pigments, being […]

When we consider a short survey of today’s major inorganic pigments, we are faced with the realization that the three major pigment families: titanium dioxide, carbon black, and iron oxides, accounting for more than 90% of the worldwide tonnage, as shown in Table 1.1, are all outside of our subject matter. They are well known […]

Gunter Buxbaum 1.1 Introduction In 2005 the world production of inorganic pigments was approximately 6 million tonnes, representing a value of about $14 billions. For high performance pigment applications the market in paints and coatings is of special interest and was esti­mated at 2.4 million tonnes representing a value of about $5.6 billions. Some years […]

High performance pigments are an important segment of the diverse and rich field of color and visual effect technology. The sub-category of pigments referred to as “high performance” generally denotes members of the larger body of pig­ments, both organic and inorganic, that exhibit enhanced durability. The most salient durability feature is generally regarded as resistance […]
