Abstract

The development of sample preparation for the determination of Si isotopic abundances ratios with gas-source mass-spectrometry is introduced. The single crystal silicon is converted to SiO₂ based on alkaline solution digestion followed by cation-exchange column and calcinating at 850°C. After dissolving SiO₂ with HF acid, H₂SiF₆ solution is obtained. BaSiF₆ precipitation is formed by drop adding BaCl₂ solution. Then BaSiF₆ is decomposed to SiF₄ and Si isotope ratios is measured by gas-source mass-spectrometry. By Optimizing the sample preparation procedure, high recovery SiF₄ gas is obtained. The results indicate that the sample preparation method for the determination of Si isotopic abundances ratios has high repeatability and recovery, meeting the requirement for the accurate measurement of silicon molar mass.
