Study of solid solutions, with perovskite structure, for application in the field of the ceramic pigments

There is a current need of different ways to obtain red colored systems. One way could be the intensification of the crystal field of the chromium(III) ion when it substitutes for aluminum(III) in the corundum structure (α-Al 2O 3). In the present work, solid solutions with perovskite structure ABO...

Description
Summary:There is a current need of different ways to obtain red colored systems. One way could be the intensification of the crystal field of the chromium(III) ion when it substitutes for aluminum(III) in the corundum structure (α-Al 2O 3). In the present work, solid solutions with perovskite structure ABO 3 were prepared in the system Nd 1− x Y x Al 1− y Cr y O 3 using both conventional solid state synthesis and coprecipitation. The synthesized structures were characterized structurally and microstructurally, thus determining the nature and purity of the resulting phases. A discussion is given in terms of crystal chemistry. Finally, the synthesized solid solutions were tested as ceramic pigments in enamels by measuring the chromatic coordinates, CIE-Lab.
