Preparation and characterisation of zinc yellow pigment for low temperature ceramic glaze – Part I: the effects of the reactants ratio, stirring time and pH

Abstract

Zinc potassium chromate (4Zn·O₄CrO₃·K₂O·3H₂O) was prepared using zinc salt solution, sodium hydroxide and potassium dichromate solutions. The pigment synthesised was investigated by various methods. Upon heating, this pigment underwent decomposition to form ZnCr₂O₄, K₂CrO₄ and ZnO. The pigment obtained was successfully used in the preparation of glaze and then on a tile. The L*, a* and b* values of the fired glaze were 71.607, 2.695 and 67.327, respectively.
