Development of Red Ceramic Pigments with Perovskite Structure Prepared through a Traditional Route

open access: yesEng, 2023
Solid solutions of ceramic pigments of red shade have been synthesized based on YAlO3 perovskite structure doped with chromium by means of conventional synthesis; that is, the “ceramic route”.

Preparation of glaze using electric-arc furnace dust as raw material

open access: yesJournal of Materials Research and Technology, 2019
Large industrial productions generate large amounts of waste, and researchers are investigating alternatives to reuse them. For instance, these wastes can used to produce ceramic pigments in the ceramic tile industry.

Iron Doped-ZrSiO4: Structural, Microstructural and Vibrational Characterization [PDF]

open access: yesMaterials Research, 2015
Fex-ZrSiO4 is known for the applications in the ceramic industry such as ceramic pigment. In this article, we focus our attention to the structural, microstructural and vibrational changes of Fex-ZrSiO4 from free-mineralizer precursors, treated at ...

Synthesis and characterization of lanthanum- and yttrium-doped Fe2O3 pigments Síntese e caracterização de pigmentos de Fe2O3 dopados com lantânio e ítrio

open access: yesCerâmica, 2007
Iron oxide has been doped with rare earth ions (yttrium or lanthanum) aiming at producing ceramic pigments with hues that vary from orange to brown. The powders were synthesized from polymeric precursors using the Pechini method and subsequently calcined

Ceramic Coatings for Pigments [PDF]

open access: yes, 2012
Special effect pigments, which can be natural or synthetic, show outstanding qualities of luster, brilliance and iridescent colour effects based upon optically thin layers [1.1–1.4]. This visual impression develops by reflection and scattering of light on thin multiple layers. In nature this is not limited to pearls and mussel shells alone; there are a

Phase and chemical composition analysis of pigments used in Cucuteni Neolithic painted ceramics

open access: yesDocumenta Praehistorica, 2007
Two analytical methods – 241Am-based X-Ray Fluorescence (XRF) and Synchrotron Radiation X-ray Diffraction (SR-XRD) – were used to investigate the elemental and mineralogical composition of pigments which decorate some Cucuteni Neolithic ceramic sherds ...

Synthesis of coloured ceramic pigments by using chromite and manganese ores mixtures Síntese de pigmentos cerâmicos coloridos usando misturas de cromita e de minérios de manganês

open access: yesCerâmica, 2010
The aim of this work is not only the synthesis of black ceramic pigment with spinel structure using local and inexpensive minerals (chromite and manganese ores) but also throw some light on the relations between the structure and the colour of obtained ...

Production and characterization of colored feldspathic enamel for dental application [PDF]

open access: yesMaterials Research, 2014
In this work we synthesized pigments capable of developing dental shades when mixed with dental porcelain and fired at appropriate temperatures. TiO2-xCeO2 pigments (x = 2, 6, 10, 13 and 18 mol%) were synthesized by the Pechini method.

Engineering Concentration‐Dependent Intravitreal Mobility via Cyclic Arginine‐Enriched Nanocarrier Surface Modification: In Vivo Proof‐of‐Concept in a Porcine Large Animal Model

open access: yesAdvanced Healthcare Materials, EarlyView.
In this study, Hammer et al. highlight cyclic‐arginine surface engineering as a highly biocompatible, controllable, and concentration‐dependent regulator of intravitreal nanoparticle mobility in vivo in a translational large animal model. The cyclic arginine surface‐modification supports the development of next‐generation biomaterials for long‐acting ...

Concentrations of lead in ceramic tableware in South Africa

open access: yesSouth African Journal of Science, 2023
Ceramic ware is used around the world, usually daily. In the past, lead was used in the glazes and decorative paints applied to ceramic ware, mainly to increase durability, impart a smooth, glasslike finish to glazes and intensify decorative pigments ...
