Its variations are quantitatively connected to the shift of the absorption band due to the charge transfer between the ligand (OH or O 2) and the Fe 3+ ion contained in goethite and/or hematite. For ochres containing both hematite and goethite, the a * co-ordinate linearly increases with ...
BACKGROUND OF INVENTION Currently used blue pigments are Cobalt blue (CoAl2O4), ultramarine (Na7Al6Si6O24S3), Prussian blue (Fe4[Fe(CN)6]3), and Azurite [Cu3(CO3)2(OH)2]. All suffer from environmental and/or durability issues: Cobalt is considered to be highly toxic. Ultramarine and...

Sie zeichnen sich durch ungewöhnliche Farbef-fekte und einen hohen metallischen Glanz aus. Daraus ergeben sich für die farbmetrische Bewertung auch neue Ansatzpunkte: Im Gegensatz zu absorbierenden Buntpig-menten reflektieren Glimmerpigmente die einfallenden Lichtstrahlen selektiv. Außerdem...
Vivianite is a phosphate mineral (Fe3(PO4)2·8H2O) with monoclinic crystal structure. In nature, it is found either in the form of crystals or various types of aggregates, commonly the earthy ones [1]. The colour of the crystals is often very dark with strong pleochroism [2], earthy...
