Ajuste del color y reflectividad solar en pigmentos rojo-anaranjados de espinelas M2- xFe2xTi1-xO4 (M=Mg, Zn)
Universidad de La Laguna (2018-06-17)La espinela inversa Mg2TiO4 (qandilita, grupo espacial Fd-3m) dopada con Co2+ presenta un color cian (verde-azulado) característico, muy distinto al de los tradicionales pigmentos azules (CoAl2O4) o violetas (Co2SiO4) ... -
Cobalt Minimisation in Violet Co3P2O8 Pigment
MDPI (2022-01-31)This study considers the limitations of cobalt violet orthophosphate, Co3P2O8, in the ceramic industry due to its large amount of cobalt. MgxCo3−xP2O8 (0 ≤ x ≤ 3) solid solutions with the stable Co3P2O8 structure were ... -
Effects of composition and furnace temperature on (Ni, Co) (Cr, Al)2O4 pigments synthesized by solution combustion route
Wiley (2017-08)The effects of composition and furnace temperature on Ni1-ΨCoΨCr2−2ΨAl2ΨO4 (0≤Ψ≤1) pigments prepared by Solution Combustion Synthesis were studied. As-synthesized samples showed spinel-like spongy structure, very easy to ... -
Green and blue materials for the ceramic industry from pink MgCoxNi1-xSiO4 (0 ≤ x ≤ 1) solid solutions
Elsevier (2022-12-09)In this study, MgCoxNi1-xSiO4 (0.0 ≤ x ≤ 1.0) solid solutions with an olivine structure were synthetized via the chemical coprecipitation method and materials with a smaller M(II) (M = Co, Ni) amount than Co2SiO4 and Ni2SiO4 ... -
Study of Cr-SnO2 ceramic pigment and of Ti/Sn ratio on formation and coloration of these materials
Elsevier (2007)In this study, CrxSn1−xO2 (0 ≤ x ≤ 0.06) and Cr0.03Sn0.97−yTiyO2 (0 < y ≤ 0.97) compositions were synthesized by the ceramic method and characterized by X-ray diffraction, UV–vis spectroscopy and CIE L*a*b* (Commission ... -
Synthesis of Ceramic Pigments by Non-Conventional Methods for New Ceramic Decoration Technologies
German Ceramic Society (2014)The ceramic tile industry increasingly commits to modernisation and implementation of new technologies in the decoration process. Current demands of advanced processes in this fi eld, such as rotational decoration, inkjet ... -
Synthesis, through pyrolysis of aerosols, of YIn1␣xMnxO3 blue pigments and their efficiency for colouring glazes
Elsevier (2011-05)Mn-doped YInO3 blue pigments have been synthesised at a much lower temperature (1100 C) than that required by the traditional solid state method (1400 C). The developed procedure, which is based on the pyrolysis at 600 ...
