摘要：
inorganic pigments containing erbium cations and based on the spinel structure of MgFe2O4 were prepared. This type of spinel compound provides pigments of red to brown colour: an increase in the content of trivalent erbium cations results in pigments of a light brown hue. The pigments displayed good resistance to sunlight but this was reduced as the content of erbium increased. Pigments prepared using mechanoactivation possessed good resistance to sunlight over a range of erbium cation content. (C) 2008 Elsevier Ltd. All rights reserved.
