Causes of colouring in iron oxide pigments / Jürgen Köhler in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 204, N° 4601 (10/2014)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 204, N° 4601 (10/2014) . - p. 14-18 Titre : Causes of colouring in iron oxide pigments Type de document : texte imprimé Auteurs : Jürgen Köhler, Auteur ; Volker Schneider, Auteur ; Jürgen Kischkewitz, Auteur Année de publication : 2014 Article en page(s) : p. 14-18 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Caractérisation Couleur -- Analyse Oxyde de fer Pigments métalliques Spectroscopie d'absorption Index. décimale : 667.2 Colorants et pigments Résumé : With an annual consumption of around one million metric tons, synthetic iron oxides are the most important group of inorganic colour pigments. Although these products have already been used very successfully to colour a wide range of materials for many years, their colouring mechanism (causes of colouring) has not been described sufficiently to date. In the case of inorganic pigments, colouring is commonly produced by a combination of light absorption and diffusion in the visible spectral range. This publication offers a detailed description of colouring for red, yellow, orange and black iron oxides. It is explained using structural features of the respective iron oxides and findings from ligand field and molecular orbital theory (MO theory). The tests performed were carried out on phase-pure iron oxide pigments that are grouped together with selected properties in Table 1. Note de contenu : - TESTS ON IRON OXIDE RED PIGMENTS : 1.

More than just rust / Ulrike Pitzer in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 199, N° 4541 (10/2009)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 199, N° 4541 (10/2009) . - p. 20-24 Titre : More than just rust : Manufacture and application or iron oxide pigments Type de document : texte imprimé Auteurs : Ulrike Pitzer, Auteur ; Volker Schneider, Auteur Année de publication : 2009 Article en page(s) : p. 20-24 Langues : Anglais (eng) Catégories : Oxyde de fer Pigments inorganiques Index. décimale : 667.2 Colorants et pigments Résumé : Iron oxides occur naturally in a variety of minerals. They are the principal components of red soils and are responsible for the typical reddish-brown colouration of rock formations like the Grand Canyon or Uluru (Ayers Rock). Yellow, black and brown minerals based on iron oxide also occur in nature and, as evidenced by the Stone Age cave paintings in Lascaux, France or Altamira, Spain, have long inspired the artistic side of man. Whereas itwas primarily natural iron oxides that were used in the past, synthetically manufatured iron oxide pigments from the late 19th century onwards have gradually displaced them, due to their greater purity and superior and more consistent quality. With an annual demand of approximately 1.1Mt, synthetic iron oxides are easily the largest group of colour pigments in terms of volume. Iron oxides are available in the colours yellow, orange, red, brown and black, with the intrinsic colour determined by the chemical modification.
