Pokraskin The continually increasing importance of iron oxide pigments is based on their nontoxicity, chemical stability, wide variety of colors ranging from yellow, orange, red, brown, to black, and good performance/price ratio. Natural and synthetic iron oxide pigments consist of well-defined compounds with known crystal structures (Table 3.1) [3.1, 3.2].
Nevertheless the inconsistency of the CAS-Numbers cannot be explained, but must be taken into consideration. Regulatory orders are using these figures concurrently! Mixed metal oxide pigments containing iron oxide are also used (see Section 3.1.3.). Magnetic iron oxide pigments are discussed in Section 5.1. Transparent iron oxide pigments are described in detail in Section 5.4.1. Methods of analysis and specifications of iron oxide pigments are listed in the standards given in Table 1.1.
