Silicon isotopes (Si)
Silicon isotopes are used in industrial applications and research applications. The stable Silicon isotopes can be enriched or depleted by Urenco Stable Isotopes to any concentration. The Silicon isotopes can be supplied in various chemical forms.
Naturally occurring silicon has three stable isotopes.
| Isotope | Maximum available enrichment (atomic %) | Natural abundance (atomic %) |
|---|---|---|
| ²⁸Si | >99.9, <1 | 92.22 |
| ²⁹Si | >99.9, <1 | 4.69 |
| ³⁰Si | >99.9, <1 | 3.09 |
Application of Silicon isotopes
Silicon 28 (Si 28)
Si-28 is under research for the improvement of the thermal conductivity of semiconductors.
Silicon 29 (Si 29)
Si-29 is used in NMR spectroscopy.
Silicon 30 (Si 30)
Si-30 is used to study the isotope effect on superconductivity, and to study the self-diffusivity of Silicon. It is also used to produce the radioisotope Si-31.
