Abstract

In this study, development of a new black pigment for colouring porcelain tiles by calcination of hematite waste and natural manganese ore mixtures were investigated as a way to produce cost-effective pigment. It was found that by incorporating 10 wt% manganese ore (containing about 75 wt% MnO2) into hematite waste (containing about 97 wt% Fe2O3), a black pigment can be obtained. The black pigment predominantly contained hematite phase indicating that manganese was dissolved in hematite structure, changing the brown colour of hematite into black colour. © 2012, Copyright The Indian Ceramic Society.
