In this study, the usability of the black colored inorganic pigment obtained by mixing MHP composite produced from laterittic nickel, chromite and magnetite ores in our country was investigated. The effects of the addition of the produced pigment to the tile glazes in different proportions and calcination were studied. It has been determined that the color values of this pigment used in tile glazes are quite similar to the black pigments used commercially and can be used in the production of 538 945 9307 Escort colored glaze for tiles. The aim of this work is not only the synthesis of black ceramic pigment with spinel structure using local and inexpensive minerals chromite and manganese ores but also throw some light on the relations between the structure and the colour of obtained pigment. Ultimate utilization spinel solid solution in ceramic materials is mostly due to their structure characteristics, their thermal and chemical stability. In this study colour pigments were ned by calcinations at ºC starting from a mixture of chromite and manganese oxide. Different compositions were tested containing 30, 40 and 50 wt. The phase composition and microstructure characterization of both raw material and obtained pigments were evaluated by X-ray diffraction, X-ray fluorescence, polarizing microscope and scanning electron microscope. Furthermore, the colour measurements of the obtained pigments and tiles were evaluated. Composition of all pigments reveal th In this study, the usability of the black colorant obtained by mixing of MHP composite produced from laterittic nickel, chromite and magnetite ores in certain proportions, in boron and leaded glazes was investigated. Prepared black colorant was added to leaded and boron glaze in varying proportions. It has been determined that the color values of this colorant used in leaded and boron glazes are quite similar to commercially used black pigments. As a result, black colorants with high added value were produced with 538 945 9307 Escort use of domestic resources and positive results were obtained in their use in leaded and boron glazes. The pigment was based on the chromeeironenickel black spinel Ni,Fe Fe,Cr 2 O 4 catalogued as in the DCMA classification and prepared by the common solid-state reaction method, under optimal formulation and processing conditions. The characterised synthesised pigments were tested in typical ceramic glazes and ceramic bodies. Optimal colour development was achieved when the spinel compound with the three elements Fe, Ni and Cr was the major phase formed. The colouring properties were similar to those imparted by 538 945 9307 Escort commercial black pigment. The thermal analysis of the precursors highlighted the thermal stability of the pigments and the mass losses, as well as the phase changes that occurred within the 25 °C temperature range. Based on the acquired data the 18 pigments were grouped, according to their thermal stability, into possible domains of application: obtaining glazed polychrome elements and water and oil based paints. Even if they were obtained from the same precursors, namely zinc phosphate and chromate, as basic materials for synthesizing ceramic pigments by doping with chromophore cations, after co-precipitation in aqueous systems the obtained pigments had different thermal behaviour. Thus, the first group contains pigments with high chemical and thermal stability, namely P. The second group, that of the less stable pigments, can be used for oil or water based painting, includes: P. The ceramic pigments were prepared using a common, solid state reaction process, with optimisation of milling and firing conditions. Characterisation was undertaken using X-ray powder diffraction, diffuse reflectance spectroscopy and application in standard ceramic glazes. The ceramic pigments were of high purity! The hue of the pigments agreed with standard expectations and optimal formulations showed better performance than some commercial pigments, perhaps due to the contribution of nickel. PurposeTo investigate the effects of the temperature of synthesis and of the thermal treatment of zinc chromate on the properties of the zinc chromate pigments. The reaction temperature was varied in order to evaluate the effect of the reaction temperature on the properties of the pigment synthesised. The pigment obtained was heated to 10°C above the critical temperature in order to investigate the effect of thermal treatment on the pigment properties. FindingsReaction temperature had a significant effect on the properties of the resulting pigment. The glaze containing zinc chromate had satisfactory colour characteristics. Research limitati In this study the efficiency of the Kubelka-Munk model already known and consolidated in other industrial sectors was evaluated in the prediction of the colour of an opaque ceramic glaze obtained by a mixture of black pigment spinel Ni-Fe-Cr and zircon opacifier ZrSiO 4. Glazes with different percentages of black pigment and opacifier were prepared to determine the absorption and scattering optical constants from the reflectance curves measured with a spectrophotometer. After the physical and chemical characterization of the glaze components frit, pigment and opacifiersuggestions for the adaptation of the Kubelka-Munk model 538 945 9307 Escort made to facilitate the experimental procedure of analysis. The result obtained with the adapted Kubelka-Munk model was in good agreement with the experimental reflectance curves.
