SYNTHESIS PIGMENT CoAl2O4 WITH PARTICLE SIZE VERY FINE AT LOW HEATING TEMPERATURE

Abstract

The reaction temperature in solid state depends on the chemical precursors. When used with the rezinates of metals cobalt and aluminum we can obtain the pigment of CoAl2O4 at very low heating temperature with particle size about 30 - 40 nm. This is the result of strong reaction between actively oxides CoO and Al2O3 as corresponding rezinates decompose.
