Abstract

In this work spinel structure CuCr2O4 was made by the alternative solution combustion method, which consists of a reaction between a fuel and an oxidizing agent. Inorganic pigment was also obtained by the method of solid state reaction, which uses a temperature of 1000 ° C and a process time of 24 h, in this case impurities of Cr2O3 were also presented. The crystal structure of synthesized powder was characterized by the technique of X-ray diffraction (XRD). The morphology of powders was determined by scanning electron microscopy (SEM). Finally, the spectrophotometry in the range visible (400 nm – 700 nm) and colorimetry CIE La*b* showed that the powders are black. It is concluded that make CuCr2O4 by solution combustion is more energy efficient than the traditional method, in the first case is used as process conditions a temperature of 700 ° C and a time of 6h, which shows that the route solution combustion technology is an alternative way to the currently used in the inorganic pigments industry
