Silicon-28
Silicon-28: Natural silicon contains 4.7% ²⁹Si, whose nuclear spin noise causes decoherence of silicon-based spin qubits. Vangas high-abundance silicon-28 isotope gas features an isotopic abundance of ≥99.99 atom% and 5N/6N electronic-grade purity.
²⁸SiF₄ serves as an intermediate for concentration and fluorination processes, while ²⁸SiH₄ acts as a direct CVD precursor for epitaxial growth of isotopically pure silicon layers.
The products are widely applied in silicon-based quantum computing, isotopic epitaxy for advanced semiconductors, research on thermal and carrier transport properties of silicon materials. High-purity ²⁸Si single crystals also support metrology research including Avogadro constant measurement and redefinition of the kilogram, catering to quantum chip R&D teams, semiconductor epitaxy production lines and advanced research institutions.
