Process parameters determination of phosphorescent pigment added, frit-based wall tiles vetrosa decorations

In this study bluish-green (BG) and yellowish-green (YG) phosphorescent pigments were synthesized and produced under laboratory conditions and the best ones in terms of higher phosphorescence intensity and longer duration were, afterwards, added into wall tile transparent vetrosa frits to obtain new, functional and decorative products. Their uses under industrial working conditions were also examined. Throughout the study the optimum process parameters were determined. (C) 2011 Elsevier Ltd and Techna Group S.r.l.
