The Effect of Calcination Temperature on Copper Aluminate and Investigation of Crystallinity Structure and Formation of Crystals

In the present study, the influence of calcination temperature on copper aluminate and investigation of crystallinity structure and formation of crystals has been studied. copper aluminate was synthesized by combustion method and glycine used as a suitable fuel for this experiment. the copper aluminate without any additional annealing (g) was compared with cual2o4 that place in the furnace for 90 minutes in 1100 degrees celsius (g1100) with at a rate of 10 degrees per minute. the synthesized pigments were specified by xrd, sem and near infrared reflectance. in sem images, the formation of crystals is clearly visible and the particle size distribution in the 1100 sample is detectable. sem images of the g1100 show a much more appropriate distribution than the g sample. also, germination is much more formed and sintering is visible between the seeds. in the x-ray images of the g1100 sample, the peak intensities are much stronger and narrower are visible than in the g sample. and the g 1100 peaks are exactly the same as the copper aluminate peaks. also, the phase of spinel formation of copper aluminate in g1100 can be seen

The copper aluminate without any additional annealing (G) was compared with CuAl2O4 that place in the furnace for 90 minutes in 1100 degrees Celsius (G1100) with at a rate of 10 degrees per minute. The synthesized pigments were specified by XRD, SEM and Near Infrared Reflectance. In SEM images, the formation of crystals is clearly visible and the particle size distribution in the 1100 sample is detectable.
