Description	This work is done in frame of EMRP project SIB10 NOTED “Novel techniques for traceable temperature dissemination”. One activity of this project is improving the current realisation of the ITS-90 by a systematic study of the uncertainties in the realization of the defining fixed points due to impurities in the fixed point materials. Phase diagrams for low impurities concentration in the fixed point material do not currently exist, so it is not possible to perform any corrections due to impurities in the fixed point temperatures. Work aims to precisely quantify the temperature effect of some common impurities in the defining metal fixed points (gallium and aluminium). The uncertainties due to impurities correspond, on average, to about 20 % of the total uncertainty. In this paper will be presented the results of doping experiments in Ga cells with Pb and Ni at 2 different concentrations in the range from (0.1 to 10) μmol/mol obtaining their corresponding phase diagrams. The results of doping experiments of Al cells with Pb and Ni at 2 different concentrations in the range from (0.1 to 10) μmol/mol obtaining their corresponding phase diagrams will be also presented.
