This work reports the results of an evaluation of the use of rice husk ash as the source of silica in thepreparation of coral ceramic pigments. ZrSiO4eFe2O3 inclusion pigments have been synthesized by solidstate reactions evaluating the effect of the mineralizer and both silica and iron oxide precursors on thereactivity of the system. The colour developed in the derived ceramic glazes has been compared with thecolour developed in comparative pigments prepared from pure SiO2.

Abstract
This work reports the results of an evaluation of the use of rice husk ash as the source of silica in thepreparation of coral ceramic pigments. ZrSiO4eFe2O3 inclusion pigments have been synthesized by solidstate reactions evaluating the effect of the mineralizer and both silica and iron oxide precursors on thereactivity of the system. The colour developed in the derived ceramic glazes has been compared with thecolour developed in comparative pigments prepared from pure SiO2.
