A Novel Synthesis For Spinel Color Ceramic Materials Using Simple And Cheap Routes At Low Temperature.

Nanocrystalline NixMg1−xAl2O4 spinel (x=0.1, 0.3, 0.5, 0.7 and 1) inorganic pigment were synthesized via low-temperature combustion route employing L-alanine as a novel environmentally benign fuel and noval fuel. After annealing the combustion synthesis powders at 500,700.900 and 1100 ˚ C for 1 h were studies. The obtained powder were characterized by means X-ray diffraction (XRD), Fourier transform infra-red spectroscopy (FTIR), diffraction thermal analysis (DTA), CIE L* a* b* color measurement and scanning electron microscope (SEM). XRD patterns shows that all calcite powder have single- phase NixMg1−xAl2O4 cubic spinel structure. All samples had blue and blue green shades, denoting the inclusion of Ni 2+
