Lanthanum cobaltite black pigments with perovskite structure

Dopant-driven tuning of toluene oxidation and sulfur resistance at the B-site of LaCo1−xMxO3 (M = Fe, Cr, Cu) perovskites

“…3(b), all the samples have obvious characteristic absorption peaks around 560 and 590 cm −1 , which may be attributed to two kinds of stretching vibration of the B–O bond in the BO 6 octahedron. 46,47 These results further verified that all the doped catalysts had an ABO 3 perovskite structure.…”

Submicronic spherical inclusion black pigment by double‐shell reaction sintering

“…As far as we know, however, it is difficult to meet “green” target due to heavy metal concerns and the recognition that Co resources are limited . Many studies about nontoxic candidate and the re‐utilization of industrial waste have emerged, aiming to solve these problems . CB (carbon black) @ZrSiO 4 inclusion pigments was positioned as a promising alternative to spinel black ceramic pigments, which has been performing well on ceramic glaze for a long time at the research level.…”

Influence of variables on the synthesis of CoFe2O4 pigment by the complex polymerization method

“…Various chemical methods, such as conventional ceramic method [2,14,15], combustion synthesis, co-precipitation [16], sol-gel method [2,17], polymeric precursor [1,18], microwave synthesis [19], and others, have been used to synthesize inorganic pigments. The complex polymerization method (CPM) based on the Pechini method offers the possibility of preparing complexes of good homogeneity at molecular scale and a good stoichiometric control.…”
