Resumo

We report the preparation of ceramic pigments using industrial wastes as primary sources.In this context, the use of Al-rich sludge generated in the wastewater treatment unit of an anodising or surface coating industrial plant, and a galvanizing sludge from the Cr/Ni plating process, will be detailed.The ceramic pigments reported here were prepared using typical solid state reactions involving the metal rich sludge.The main focus will be on the synthesis of chrome-tin orchid cassiterite (Sn,Cr)O 2 , chrome-tin red malayaite Ca(Cr,Sn)SiO 5 , victoria green garnet Ca 3 Cr 2 Si 3 O 12 , and chrome alumina pink/green corundum (Cr,Al) 2 O 3 pigments.The pigments were fully characterised and then were tested in a standard ceramic glaze after.Typical working conditions and colour development will be reported.
