Abstract Large-scale silicon isotope separation based on the IRMPD of natural Si2F6 has been carried out using a commercially available high power CO2 TEA laser and a flow reaction system. The decomposition product SiF4 containing 19–33% of 30Si was obtained at a production rate of 1.5×10−2−2.6×10−2 mol·h−1, depending on experimental parameters such as laser wavelength, laser fluence, pressure, and flow rate. SiF4 containing 12% of 29Si was obtained under slightly different conditions, i.e., at a shorter wavelength than that for 30Si. When 39% of Si2F6 was decomposed at a slow flow rate, residual Si2F6 was found to have 99.7% of 28Si. The production rate was 4.2×10−2 mol·h−1.
