Obtaining and Characterisation of Thermoresistive Pigments
Journal Title: Analele Universitatii "Dunarea de Jos" din Galati. Fascicula IX, Metalurgie si Stiinta Materialelor - Year 2009, Vol 32, Issue 2
Abstract
The paper describes the obtaining and chemical and physico-structural characterisation of a green thermoresistive pigment. The pigment is made of ZnO dopped with Sb, Bi, Cr, Co and Fe oxides and it is used at mosaics and stained glass. The procedure is based on a sequential coprecipitation “layer on layer” process in aqueous solution, followed by drying and calcinations at controlled temperature conditions, then grinding in a colloidal mill and mixed with glass powder forming the “frit pigment”. This by vitrification and frosting colours superficial the glass. The powder was analysed by SEM-EDX and DSC.
