High-Purity Copper Ingots (6N)
Cu ingot · claimed purity 99.9999%
Isotopically pure semiconductors have higher thermal conductivity and a “quiet” spin environment. High-purity metals are needed for sputtering targets, microelectronics and cryogenic equipment.
| Isotope | Element | Enrichment, at.% | Application |
|---|---|---|---|
| ²⁸Si | Silicon | 99.80 | monoisotopic silicon-28: quantum computing (host for spin qubits), mass standard — the Avogadro project, materials with higher thermal conductivity |
| ²⁹Si | Silicon | 88.30 | NMR spectroscopy (²⁹Si nucleus), materials research |
| ³⁰Si | Silicon | 91.30 | neutron transmutation doping of silicon with phosphorus, research |
| ⁷⁰Ge | Germanium | 97.00 | isotopically pure germanium for semiconductor physics and thermal conductivity research |
| ⁷⁴Ge | Germanium | 99.20 | isotopically pure germanium for semiconductor physics, target for radionuclides |
