Abstract: The work presented in the article is a detailed study of the optimization of the sample preparation procedure for the conversion of highly enriched 28Si single crystal into gaseous silicon tetrafluoride. This optimization is of key importance in avoiding the contamination of enriched 28Si samples with silicon of natural isotopic composition. The preparation of 28Si samples is one of the largest contributors to the combined standard uncertainty of silicon isotope ratio measurements. The optimal conditions obtained within this study will later be used in the preparation of silicon synthetic isotope mixtures which are needed for the calibration of Si isotope ratio measurements.
