“…EAFD is popular in the production of various structural materials, improving their properties and binding heavy metal compounds. EAFD is used in the production of cement concretes [6], asphalt concretes [7], ceramics [8], glass ceramics and glazes [9], and even ink [10]. EAFD can be used in agriculture for soil deoxidation due to the content of oxides of alkali and alkaline earth metals [11].…”

The production of three-phase composites is a relevant and effective approach to obtain materials with the required mechanical and dielectric properties. In this work, dust, which is a waste product of steelmaking and is formed during the gas cleaning of electric arc furnaces at the production base of Severstal, was used as a functional filler for the low-density polyethylene polymer matrix. The fractional, elemental, qualitative, and quantitative phase composition of the native dust was studied using laser diffraction, energy-dispersive X-ray phase analysis, and X-ray fluorescence spectrometry. An increase in the permittivity of the dust was achieved due to its reduction in a hydrogen atmosphere and, as a consequence, a change in the elemental and phase composition causing an increase in the concentration of metallic iron. Composite films were obtained using a blending roll mill at temperatures of 130 and 140 °C. The concentration of the main filler was 18.75, 37.5, and 75 wt.%. Additionally, a conductive additive in the form of MWCNTs was introduced into the composition of the composites in an amount of 0.25 wt.%. The uniformity of the filler distribution in the polymer matrix was assessed from electron micrographs. The dielectric properties of fillers and composite films based on polyethylene filled with electric arc furnace dust and MWCNTs were studied using impedance spectroscopy in the frequency range of 10–106 Hz. The use of reduced dust at a concentration of 25.8 vol.% combined with 0.25 wt.% MWCNTs in the composition of the composite film provided an increase in ε′ to 13.5 at tan δ = 0.038. Thus, three-phase polymer matrix composites based on LDPE using dust as a filler with a conductive microadditive of MWCNTs have a synergistic effect, which manifests itself in an increase in the permittivity and a decrease in dielectric losses.

“…Recently, ink-jet printing technology has gradually matured and has been applied to the ceramic industry [1][2][3]. However, due to the limitation of inorganic pigments, the colors of printed products are still not rich enough, especially the bright and pure red inks are always blank [4], and only Fe-Cr-Zn brown-red pigments or Zr-Fe red pigments (dark red) can barely be used to adjust the color [5,6].…”

Cadmium selenide sulfide (CdSxSe1-x) encapsulated by zirconium silicate (ZrSiO4) (CdSxSe1-x@ZrSiO4) has been widely considered in ceramic pigments for ink-jet printing but suffer from big particle size and dark hue troubles. Herein, an integrated liquid approach was developed, which gives CdSxSe1-x@ZrSiO4 pigment a uniform size, bright and pure red hue, and good wear resistance. This new strategy can effectively control the grain size of the encapsulated pigment from the dispersibility of the sol system, the ratio of material, the sintering conditions, and the selection of raw materials. The developed pigment has been successfully used in ink-jet printing and commercialized. This study paves an integrated liquid approach to improve the compatibility of wear-resistant and bright red CdSxSe1-x@ZrSiO4 pigments in ceramic ink-jet printing.
