Enriched stable isotopes of silicon (Si, Z = 14): 3 isotopes with enrichment up to 99.80 at.% (²⁸Si). Chemical form: oxide. Packaging from milligrams; every lot comes with a passport stating its isotopic and chemical composition.
| Isotope | Enrichment, at.% | |
|---|---|---|
| ²⁸Si | 99.80 | |
| ²⁹Si | 88.30 | |
| ³⁰Si | 91.30 |
Enrichment is the atomic fraction of the target isotope, %. Data are given according to the producer’s specification; the exact composition of a lot is stated in its passport. Availability, packaging and price on request. Export of isotope products is subject to export control requirements.
| ²⁸Si | monoisotopic silicon-28: quantum computing (host for spin qubits), mass standard — the Avogadro project, materials with higher thermal conductivity |
| ²⁹Si | NMR spectroscopy (²⁹Si nucleus), materials research |
| ³⁰Si | neutron transmutation doping of silicon with phosphorus, research |
Reference information on typical applications. Please confirm the suitability of the isotope for your task (enrichment, chemical form, quantity) in your request.
