Characterization of Ba2+-added alumina/cobalt nanoceramic pigment prepared by polyacrylamide gel method
Source abstract
Abstract
Abstract Nanocrystalline Ba 2+ added alumina/cobalt blue nanoceramic pigment was prepared using a polyacrylamide gel method. The samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and UV–vis spectroscopy. The XRD patterns indicated the characteristic peaks of the spinel structures related to the CoAl 2 O 4 and BaAl 2 O 4 phases with a good crystallinity. The crystallite sizes of spinels increased with the increase of barium content. The partial substitution of Co 2+ by bigger ions like Ba 2+ can cause a distortion in the unit cell compared to pure CoAl 2 O 4 sample. UV–vis analysis showed that at a wavelength of 450 nm the absorbance of the sample was changed with the increase of Ba content and yielded a blue pigment with an improved color point.
