New Ceramic Pigments for the Coloration of Ceramic Glazes

Abstract

In this communication we provide some examples of hot research topics in the field of ceramic pigments. The more classical approach of finding new host lattices or chromophores is first illustrated with recent examples of new formulations for yellow-orange, reddish-brown and blue ceramic pigments based on pseudobrookites and related titanates. Then we highlight the advantages of using non-conventional preparation routes, which can provide different pigmenting alternatives for the emerging ink-jet printing technology, such as the development of nanoor sub-micron pigments and “ceramic inks”, or the use of appropriate precursors forin situ-generatingpigments.

Synthesis and coloring performance of Ni-geikielite (Ni,Mg)TiO3 yellow pigments: Effect of temperature, Ni-doping and synthesis method

“…of the still limited pallet of commercially available ceramic pigments [1,2]. Within the last decades, many investigations are being conducted to improve synthesis methods and to develop high-performance ceramic pigments [3,4], enabling their use in high-temperature glazes (above 1200 • C) and also the preparation of coloring ceramic inks for inkjet printing technologies [1,5].…”

Synthesis of Green Brucite [NixMg1−x(OH)2] by Incorporation of Nickel Ions in the Periclase Phase (MgO) Applied as Pigments

“…Compared to β-Ni(OH) 2 , the O-H bond becomes less polarized with a higher concentration of Mg in the lattice, shifting the ν(OH) band to higher wavenumbers [35]. Therefore, the difference in electronegativity of Mg [14,16] and Ni [6,16] promotes the exchange of Mg for Ni in the crystalline structure [35].…”

“…Furthermore, metal oxides and hydroxides serve as common hosts for transition metal chromophores in the inorganic pigments field [14][15][16]. The variation of the supporting structure or transition metal chromophores constitutes a methodology to enhance known inorganic pigments or synthesize novel ones, envisioning the implication on economics, efficiency, and ecological aspects [14].…”

Preparation of green brucite [NixMg1-x(OH2)] resulting from the combination of nickel ions and periclase (MgO) applied against yeast and bacteria

“…Usually in the field of inorganic pigments metal oxides are closely attached to the subject, may it be by researching to synthetize new pigments by combination of chromo-phore, usually metals, with diverse support structures, example metal oxides, new syn-thetic routes, or optimization of already know pigments properties [1,2].…”
