Powder silica and elemental silicon enriched with 30Si were prepared at the request of nuclear physicists who had needed the isotopic samples for their research on neutron-rich nuclei. The enrichment of 30Si was performed by means of the IRMPD of Si2F6to SiF4using a CO2laser. The 30Si-enriched SiF4was further converted either to silica by hydrolysis with aqueous ammonia or to silicon by LiAlH4reduction to SiH4followed by its thermal decomposition. As the final products we obtained 11.35 g of silica with 20.6% 30Si, and 3.06 g of silicon with 17.5% 30Si. |
