“…Though the above concerns are not included in V-ZrSiO 4 , the limited b* value in its light blue color is not satisfactory. 8 Blue stands as the most prevalent color in various applications, with cobalt blue emerging as the in the monoclinic structure is wholly connected with [SiO 4 ] and forms a three-dimensional network of tetrahedrons. At the same time, the Ba 2+ ions are interspersed between the upper and lower sets of oxygen-bridged Al−Si double tetrahedrons, as illustrated in Figure 1.…”

Blue pigments and blue glazes play crucial roles in our daily life. Ongoing research into blue pigments aims at environmentally friendly compositions with a lower cost. In this work, Co-doped BaAl 2 Si 2 O 8 pigments were synthesized by a solid-state method. The blue color of the pigments is due to the 4 A 2 ( 4 F) → 4 T 1 ( 4 P) transitions allowed by doped Co 2+ in the tetrahedral coordination of the structure. The pigments exhibit excellent stability under both acidic and alkaline conditions. When combined with transparent glazes, BaAl 2−x Co x Si 2 O 8 demonstrates satisfied compatibility, resulting in blue glazes with a significant reduction in Co content compared with existing formulations. Furthermore, BaAl 2−x Co x Si 2 O 8 blue glazes possess a simple production route, commendable color performance, and cost-effectiveness.

“…The too-high temperature required for the formation of a dense protective coating is extremely unfavorable for BiVO 4 due to its poor thermal stability; at these temperatures, the volatilization of V and thus the alteration of the phase structure and color of the pigment would be unavoidable. Furthermore, the V ions in BiVO 4 can react easily with zirconium hydroxide, one of the precursors for synthesizing ZrSiO 4 or ZrO 2 , which brings about a significant color change in the pigment [26,27]. Thus, in the present work, SiO 2 was selected to encapsulate BiVO 4 pigments due to the lower temperature to form a dense surface protective coating.…”

The preparation of environmentally friendly inorganic encapsulated pigments with a bright color and sufficient stability provides an effective strategy for expanding their applications in plastic, paint, glass, and ceramic decoration. The challenges facing the use of such pigments include the formation of a dense protective coating with the required endurance, the relatively weak color of the encapsulated pigments, and the preferable inclusion particle size. Environmentally friendly BiVO4 is regarded as a very promising pigment for multiple coloring applications due to its brilliant yellow color with high saturation. However, its poor thermal and chemical stability greatly limit the application of BiVO4. Herein, we report a sol–gel method to synthesize inorganic BiVO4@SiO2 yellow pigment with a core–shell structure. By controlling the synthesis conditions, including the particle size and dispersion of BiVO4 and the calcination temperature, a BiVO4@SiO2 encapsulated pigment with excellent chromatic properties was achieved. The obtained environmentally friendly BiVO4@SiO2 pigment with encapsulation modification has a comparable color-rendering performance to BiVO4, and it has a high thermal stability at 700 °C, excellent acid resistance, and good compatibility in plastics. The present research is expected to expand the application of yellow BiVO4 pigment in harsh environments.

“…According to the distinction of the coloring mechanism, zircon pigments are generally divided into two subcategories: (I) heteromorphic zircon pigments (HMZPs), represented by the brilliant red CdSe x S 1- x @ZrSiO 4 , yellow CdS@ZrSiO 4 , carbon-black C@ZrSiO 4 and iron-red Fe 2 O 3 @ZrSiO 4 (Qin et al , 2021; Chen et al , 2019; Cannio and Bondioli, 2012); (II) ion-substitutional zircon pigments (ISZPs), typically as the yellow Pr–ZrSiO 4 , green Cr–ZrSiO 4 and the blue V–ZrSiO 4 (Yang et al , 2021; Zhang et al , 2021; Guo et al , 2018; Li et al , 2019).

Purpose This paper aims to systematically demonstrate a methodology to determine the relative and absolute encapsulation efficiencies (αRe and αAb) for thermally- and chemically-robust inorganic pigments, typically like ZrSiO4-based pigments, thereby enhancing their coloring performance. Design/methodology/approach The authors designed a route, surplus alkali-decomposition and subsequently strong-acid dissolution (SAD2) to completely decompose three classic zircon pigments (Pr–ZrSiO4, Fe2O3@ZrSiO4 and CdS@ZrSiO4) into clear solutions and preferably used inductively coupled plasma-optical emission spectrometry (ICP-OES) to determine the concentrations of host elements and chromophores, thereby deriving the numeric data and interrelation of αRe and αAb. Findings Zircon pigments can be thoroughly decomposed into some dissoluble zirconate–silicate resultants by SAD2 at a ratio of the fluxing agent to pigment over 6. ICP-OES is proved more suitable than some other quantification techniques in deriving the compositional concentrations, thereby the values of αRe and αAb, and their transformation coefficient KRA, which maintains stably within 0.8–0.9 in Fe2O3@ZrSiO4 and CdS@ZrSiO4 and is slightly reduced to 0.67–0.85 in Pr–ZrSiO4. Practical implications The SAD2 method and encapsulation efficiencies are well applicable for both zircon pigments and the other pigmental or non-pigmental inhomogeneous systems in characterizing their accurate composition. Originality/value The authors herein first proposed strict definitions for the relative and absolute encapsulation efficiencies for inorganic pigments, developed a relatively stringent methodology to determine their accurate values and interrelation.
