Research on new ceramic dyes is addressed to obtain best pigmenting materials in
order to reach higher thermal stability (e.g. for porcelainised stoneware) than classical
pigments, higher chemical stability towards the coloured matrix or low toxicity in order to
satisfy health and environmental requirements. The earlier developments on the research in
new ceramic pigments based on new crystal structures (e.g. perovskite, hexaaluminates,
fergusonite, pseudobrookite …), new chromophores (e.g. ruthenium, bismuth and rare earth
ions), or new methods of preparation are discussed in this communication.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
