Glass and Ceramics, 1986
The authors assess the corrosion resistance, crystal structure, chemical composition and color properties of a variety of zircon-based materials used as pigments and protective coatings for ceramic tiles. The constituents of these materials include, apart from zircon, iron oxides, vanadium oxides, and the sulfides, selenides and tellurides of cadmium ...

Ceramic Pigments with Perovskite Structure
Advances in Science and Technology, 2006The results of preliminary investigation on preparation of perovskite pigments by solid state reaction are presented. The effects of different raw materials used as component carriers on formation of colored pigments were examined. Pigment composition, optimum chromophore addition, type of mineralizer and the conditions of synthesis were determined ...

Nonstoichiometric reactions producing ceramic pigments
Glass and Ceramics, 2011The reactions synthesizing diopside ceramic pigments using natural minerals—talc and wollastonite—have been investigated. For the initial components taken in a nonstoichiometric ratio the yield of the main reaction product — diopside — increases in two of the three reactions studied, while in the third reaction a change of the stoichiometry of the ...

CERAMIC PIGMENTS ARE COMPLEX MIXTURES of oxygen-containing materials that have been calcined at high temperatures to form specific crystalline phases [1]. In most cases, oxide raw materials are carefully mixed and then calcined in either batch kilns or continuous calciners [2].

Stability of ceramic pigments for maxillofacial applications
Journal of Oral Rehabilitation, 1987SummaryIn this study samples made from pigmented porcelain and Silastic 44210 were evaluated for colour stability after accelerated ageing in order to determine the potential of coloured ceramic powders as maxillofacial pigments. These pigments demonstrated good clear colour stability compared with the same pigments which were not incorporated into a ...

New Ceramic Pigments for the Coloration of Ceramic Glazes
Advances in Science and Technology, 2014In 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.

Zeolites: Raw material for ceramic pigments
Glass and Ceramics, 1998The possibilities of using natural zeolite for synthesizing ceramic pigments are investigated. The special features of isomorphism of bi- and trivalent cations in the zeolite lattice are analyzed. It is shown that it is possible to obtain pigments with the structure of anorthite and mullite using a zeolite structure with additives (alumina ...

Ceramic Pigments for Producing Black Glazes
Glass and Ceramics, 2005A new black-color ceramic pigment has been developed on the basis of the CoO - Fe2O3 system under a decreased temperature of synthesis (1000 – 1200°C). The optimum temperature range of the spinel-forming reaction in the specified oxide system is determined.

Titania slag as a ceramic pigment
Dyes and Pigments, 2008The phase transformations and colouring mechanisms that occur during the ceramic processing of titania slag were investigated using XRF-EDS, XRD, DRS and laboratory-scale application in glazed and unglazed tiles. The slag transforms to pseudobrookite, undergoing a drastic colour change during firing as a consequence of thermal oxidation with Fe2+ to ...

Monoferrite BaFe2O4 applied as ceramic pigment
Ceramics International, 2007Abstract This work had the objective of studying the ceramic pigment BaFe 2 O 4 , which presents iron as the chromophore ion, and barium as net modifier. Synthesis was done by the polymeric precursor method. After calcination at different temperatures, characterizations were done by X-ray diffraction, infrared spectroscopy, surface area by BET ...
