Abstract:Mixed spinel pigments Ni 1− Ψ Fe Ψ Cr 2 O 4 (0 ≤ Ψ ≤ 1) were synthesized by means of a method known as Solution Combustion Synthesis, using urea as fuel. Effects on mineralogy, microstructure and colouring power of composition and parameters of post-synthesis thermal treatments (temperature and kiln atmosphere) were studied. The as-synthesized powders were calcined at two different temperatures (800 and 1000ºC) and atmospheres (oxidizing and inert). Powders were characterized by Xray diffraction (XRD), thermog… Show more
“…The synthesis and processing of the basic ceramic electrodes (BCE) were well described in previous works elsewhere [36]. Both ferrite powders were synthesized by the solution combustion synthesis process that was already employed for spinel-type pigments [37,38]. A mixture of iron nitrate and Cd or Zn nitrate were dissolved in distilled water under stirring conditions.…”
