“…Yellow iron oxide pigments have a composition of α‐FeOOH and the structure of goethite, and it has long been used as a coloring material, known popularly as goethite, loess, and ocher. Because of the special weather resistance, strong tinting strength, chemical stability, and low cost, yellow iron oxide pigments have been used to color paints, inks, rubber, and plastic as well 1 . Also, because it is free from toxicity, further applications include coloration of cosmetics, roll papers for tobacco filters, and chicken feed.…”

In order to widen the application of iron oxide yellow pigments (α‐FeOOH) in high temperature industry, α‐FeOOH coated with calcium phosphate (α‐FeOOH/Ca) were modified with stearic acid (Sa) through dry process. Scanning electron microscope (SEM), transmission electron microscope (TEM), X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FT‐IR), X‐ray photoelectron spectroscopy (XPS), and thermogravimetry (TG) were employed to characterize the effect of surface modification. The effects of Sa dosage on the thermal resistance of α‐FeOOH/Ca after modification were also discussed. The crystal structure of α‐FeOOH/Ca does not change after modification with Sa, but the ratio of length to diameter about α‐FeOOH/Ca is smaller. Sa can react with α‐FeOOH/Ca in the form of –COOCa and HPO42− based on FT‐IR and XPS analyses. TG‐DTG results suggest that calcium phosphate and Sa improve the thermal stability of α‐FeOOH. The value of color difference of modified α‐FeOOH/Ca first decrease and then increase with increasing of Sa dosage, which is studied by CIE ΔL, Δa, and Δb colorimetric analyses. The amount of Sa affects the thermal resistance and dispersion performance of α‐FeOOH/Ca simultaneously; also the relationship between thermal resistance and dispersion is inversely proportional. Experimental characterizations reveal that introduction of the phosphates and Sa not only prevents the loss of water on the surface of α‐FeOOH but improve its activation index and dispersibility in organic solvents.

“…The use of industrial wastes, some of them hazardous, to synthetize inorganic pigments for ceramic applications has been a topic explored in the last years [3,4,5,6,7,8,9,10,11,12,13]. Some examples of industrial wastes used as secondary raw materials for the pigment’s synthesis include: titanium slag [3], ashes from anaerobic treatment of municipal sewage [4], electroplating sludge [5,6,7,8,9], leather sludge [10,11], red mud [7,12], and rice husk biomass [13].…”

Waste-Based Pigments for Application in Ceramic Glazes and Stoneware Bodies

The use of wastes, some of them hazards, as raw materials of ceramic pigments has been a way to diminish their environmental impact, to economically valorize them, and to face the depletion of virgin raw materials. In this work were prepared pigments having in their composition only industrial wastes: Cr/Ni electroplating (ES), and sludges from the cutting of natural stones—marble (MS) and granite (GS). The prepared mixtures were calcined at three temperatures (1100, 1200, and 1300 °C) and the obtained powders were characterized by XRD and UV-vis. Their coloring strength and thermal stability were assessed by adding them to different ceramic substrates: glazes (transparent bright and opaque matte) and a stoneware paste. The CIEL*a*b* coordinates of the fired materials were measured. The developed pigments are thermally stable and exhibit good tinting power, originating nicely colored and defect-free ceramic materials.

“…6 Most of the experimental procedures proposed in the literature for iron waste recycling deal with the synthesis of other materials and not perovskites. For example, waste ferrous sulfate from titanium dioxide industry, 7 heavy tonnage iron-removal sludge waste, 8 oily cold rolling mill sludge, and ashes of scum from anaerobic treatment of municipal sewage 9 have been used as inorganic precursors for preparing iron-based pigments or hematite nanoparticles. Recently, rusted iron coil and stainless steel wires have also been used for preparing hematite film with water oxidation and oxygen evolution activity.…”

“…20 In fact, most of the procedures proposed in the literature to recycle the waste iron make use of extraction by strong acids to dissolve the solid iron precursor. 9,14,15,21 For the sake of comparison, reference LaFeO 3 powder was also prepared by solution combustion synthesis using a commercial iron nitrate precursor. Several characterization techniques were used in this work to understand in detail the effect of the waste iron precursor amount on the chemical–physical properties of the obtained LaFeO 3 powders and to compare the waste iron precursor with the commercial one.…”

Insoluble rust waste from the scraping of rusted iron-containing materials represents a cheap, eco-friendly, and available source of iron. LaFeO 3 perovskite-type powders were successfully prepared by solution combustion synthesis using rust waste from an electricity transmission tower manufacturer. Solution combustion synthesis enabled introduction of this insoluble iron precursor directly into the final product, bypassing complex extraction procedures. Catalytic activity in the propylene oxidation of the waste-derived LaFeO 3 with stoichiometric Fe/La ratio was almost identical to the commercial iron nitrate-derived LaFeO 3 , thus demonstrating the viability of this recycling solution. The amount of waste iron precursor was varied and its effect on the powder properties was investigated. A lesser stoichiometric amount of precursor produced a LaFeO 3 –La 2 O 3 binary system, whereas a higher stoichiometric amount led to a LaFeO 3 –Fe 2 O 3 binary system. Catalytic activity of iron-rich compositions in the propylene oxidation was only slightly lower than the stoichiometric one, whereas iron-poor compositions were much less active. This eco-friendly methodology can be easily extended to other iron perovskites with different chemical compositions and to other iron-containing compounds.
