Modelling the freezing behaviour of ITS-90 metal fixed points for better understanding of the influence of impurities and thermal effects

The methods currently used by metrologists for estimating the influence of impurities in metal fixed points require accurate knowledge of the concentrations of impurities present and of liquidus slopes of binary systems. In this thesis, two alternative methods are presented that can estimate the inf...
