Uncertainty Evaluation of Alumina Content in Siliceous Refractory Materials
Inductively coupled plasma atomic emission spectrometry has the advantages of fast analysis,high accuracy and simultaneous determination of multiple elements.In this paper,the uncertainty of alumina content in silica refractories was systematically discussed by inductively coupled plasma atomic emission spectrometry,and the relevant mathematical model was established.By analyzing and evaluating a series of sources of uncertainty,reference is provided for the uncertainty analysis of other element contents in refractory materials.
