A promising hybrid pigment with bright blue for ceramics, water based paints, inks

Chineese researchers prepared  bright blue CoAl2O4/halloysite hybrid pigments via combining chemical co-precipitation and calcination process. The introduction of halloysite not only decreased the calcining temperature for formation of spinel-type CoAl2O4, but also enhanced the color properties of CoAl2O4 pigments including hue, brightness and chroma. The hybrid pigments could be well dispersed into water-based paint with good suspension stability. It indicated that the hybrid pigments could be served as a promising pigment with bright blue to be applied in various fields such as ceramics, water based paints, inks, etc.
