Anion Exchange Synthesis of Spinel-Type Cobalt-Containing Pigments

A method is proposed for synthesizing ultramarine blue pigment by co-precipitation of cobalt and aluminum from nitrate solutions by the anion exchanger AV-17-8 in the OH form followed by roasting a precursor at 750°C for 4 h. The product obtained was studied by thermographic and x-ray radiographic a...

Zusammenfassung:	A method is proposed for synthesizing ultramarine blue pigment by co-precipitation of cobalt and aluminum from nitrate solutions by the anion exchanger AV-17-8 in the OH form followed by roasting a precursor at 750°C for 4 h. The product obtained was studied by thermographic and x-ray radiographic analyses as well as by spectrophotometry (IR and diffuse reflection). Electron microscopy shows the pigment particles to be 50 – 80 nm in size.
