Novel and Environmentally Friendly (Bi,Ca,Zn)VO4 Yellow PigmentsNovel and Environmentally Friendly (Bi,Ca,Zn)VO4 Yellow Pigments

Authors: Masui, T. Honda, T. Wendusu, Imanaka, N. Source: Dyes and Pigments , In press , 2013 Bi1-x-yCaxZnyVO4-(x+y)/2 (0 = x = 0.10, 0 = y = 0.10) pigments were synthesized as novel inorganic yellow pigments that are environmentally friendly, and their color properties were characterized. The Bi1-x-yCax- ZnyVO4-(x+y)/2 pigments exhibited brilliant yellow colors, and using the CIE L*a*b* system, the most vivid yellow hue was obtained for Bi0.90Ca0.08Zn0.02VO3.95 […]

Effect of the milling process on the properties of CoFe2O4 pigmentEffect of the milling process on the properties of CoFe2O4 pigment

Authors: Hasan Yüngevis, Emel Ozel Source: Ceram. Int. , 39, 5 (5503–5511) , 2013 In this study, CoFe2O4 pigments were synthesised using both co-precipitation and conventional ceramic methods. Pigment particles prepared using the conventional ceramic method were subsequently milled to submicron size. The effects of the solvent, dispersant and milling type in the milling process were investigated. This study showed that planetary milling in a diethylene glycol (DEG) medium […]

Ni-free, black ceramic pigments based on Co-Cr-Fe-Mn spinels: a reappraisal of crystal structure, colour and technological behaviourNi-free, black ceramic pigments based on Co-Cr-Fe-Mn spinels: a reappraisal of crystal structure, colour and technological behaviour

Authors: Dondia, M. Zanellia, C. Arditb, M. Crucianib,G. Mantovanic, L. Tribaudinoc, M. Andreozzid, G. B. Source: Ceram. Int.Ceramics International , In Press , 2013 A reappraisal of crystal structure, optical properties and technological behaviour of black spinels in the Co-Cr-Fe-Mn system was carried out to define the best compositions and disclose the role of crystal chemistry in colouring performance and pigment-glaze interactions. Twenty ternary and quaternary spinel formulations were […]

New Purple-Blue Ceramic Pigments Based On Cozr4(Po4)6New Purple-Blue Ceramic Pigments Based On Cozr4(Po4)6

Authors: Nataliia Gorodylova, , Veronika Kosinová, Žaneta Dohnalová, Petr Belina, Petra Šulcová Source: Dyes and Pigments , in press , 2013 Due to the outstanding stability and resistivity to dissolution agents of the compounds related to NaZr2(PO4)3 (NZP family), our attention has been focussed on CoZr4(PO4)6 and its performance as an inorganic pigment for coloration of ceramic glazes. Mixed cobalt zirconium phosphate has been prepared by a solid state […]

Interaction of the chromium-Iron black pigment with porcelanised stonewareInteraction of the chromium-Iron black pigment with porcelanised stoneware

Authors: Mestre, S.|Gómez, P.|Gazulla, M.F.|Gozalbo, A. Source: Ceram. Int. , EN PRENSA ACEPTADO A study has been undertaken of the interaction between the (Fe,Cr)2O3 black pigment and an industrial porcelanised stoneware composition at its firing temperature. The results indicate that the glassy phase that forms during firing preferentially extracts Fe2O3 from the pigment and probably contributes some Al2O3 to it, enriching the pigment composition in Cr2O3, without changing […]

Compositional and chromatic properties of strontium hexaferrite as pigment for ceramic bodies and alternative synthesis from wiredrawing sludgeCompositional and chromatic properties of strontium hexaferrite as pigment for ceramic bodies and alternative synthesis from wiredrawing sludge

Authors: Hajjaji, W; Pullar, RC; Zanelli, C; Seabra, MP; Dondi, M; Labrincha, JA Source: Dyes and Pigments , 96 (3), 659-664 , 2013 This paper reports a new black pigment based on strontium M-type hexaferrite (SrM) obtained from pure reagents or by the inclusion of Fe-rich wiredrawing sludge. The fired powders show a clear predominance of SrFe(12)O(19). Also, haematite (alpha-Fe(2)O(3)) and iron spinel were detected in variable amounts. These […]

New results in the characterization by Raman spectroscopy of yellow pigments used in ceramic artworks of the 16th and 17th centuriesNew results in the characterization by Raman spectroscopy of yellow pigments used in ceramic artworks of the 16th and 17th centuries

Raman Spectrosc. , 43(11), 1805-1810 , Nov 2012 This investigation is focused on the identification in ceramic artworks of certain nonstandard yellow/orange pigments whose composition is based, fundamentally, on lead, tin, and antimony oxides with or without silica. In this work, a comparative study (temporal and geographical) of the employment of these yellow pigments in different production centers, from Italy […]
