Abstract :This study shows the possibility to synthesis ceramic pigments  via solid-state high temperature sintering. The preparation of high temperature ceramic pigments using colourless stable crystal carcasses turns out to be quite suitable method in the case of ZrSiO 4 and their colouring by introducing different chromophores. The paper reports for experiments carried out on the synthesis of zircon pigments with the participation of following chromophore ions: Fe 3+ , Co 2+ , Ni 2+ using the technology of solid phase sintering. Many analyses were used to determine the phase composition and check the chromophore ions valency state at temperature higher than the optimal temperature of synthesis. The colour of the pigments was determined using a Lovibond Tintometer RT 100 Color. The willemite ceramic pigments and rice husk ash were studied by X-ray analysis,  scanning electron microscopy insert ignore into journalissuearticles values(SEM);. It has been found that the synthesized pigments are suitable and can be successfully applied in glaze tiles and sanitary ceramics.The results obtained indicated that it depends on the sintering temperature isothermal soaking and the type of chromophore ion. In most pigments, the basic phase was obtained as low as 900 - 1000 0 C. The best pigments obtained were added to white faience glaze.
