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

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 obtai...

Zusammenfassung:	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.
