Improvement of the mechanical and aesthetic properties of a coating by inkjet technology

Abstract

Different amounts of ink, made up almost entirely of a frit that devitrified abundant small crystals of anorthoclase, were applied by inkjet printing onto a traditional unfired glaze substrate. The rheological properties of the ink and porous texture of the unfired glaze substrate were characterized. The fired coatings were analyzed by SEM-EDX to determine the elemental composition at different surface depths, and their microstructure was observed. The results confirmed the validity of the ink penetration model, developed in a previous study, for describing the composition profile How to cite this article: Amorós JL, Blasco E, Moreno A, Feliu C, Boschi AO, Marín N.

Effect of particle size distribution on the evolution of porous, microstructural, and dimensional characteristics during sinter-crystallisation of a glass-ceramic glaze

“…Absence of open porosity is an essential requirement for any type of glaze. In addition, closed porosity must be as low as possible, as it always adversely affects any coating's mechanical properties [1] [2].…”
