ASP Isotopes Inc. has commenced commercial production of enriched Silicon-28 at its second Aerodynamic Separation Process (ASP) facility in Pretoria, South Africa. The company expects to ship initial commercial quantities in the second quarter of 2025 and has already secured purchase agreements with two U.S.-based customers for kilogram-scale supplies. Additional discussions are underway with other potential buyers globally.
Silicon-28 is gaining attention for its potential applications in quantum computing and advanced semiconductors. Unlike Silicon-29 which has a ½ positive spin that can cause quantum decoherence, Silicon-28 is spin-free, making it potentially valuable for protecting quantum information. Research also indicates Silicon-28 exhibits approximately 150% better thermal conductivity than natural silicon, which could enable smaller and more efficient semiconductor chips for AI applications.
The company’s proprietary ASP technology directly enriches silane (SiH₄), distinguishing it from competitors who typically process silicon tetrafluoride (SiF₄) or halo silanes. This direct approach avoids additional chemical conversion steps that can compromise purity, potentially delivering higher quality material to semiconductor manufacturers. ASP Isotopes is also developing capabilities to enrich other isotopes for healthcare and energy applications using its Quantum Enrichment technology.
With quantum computing and AI driving demand for specialized materials, ASP Isotopes’ commercial production of Silicon-28 represents a significant step in supplying the semiconductor industry. The company continues to negotiate additional supply agreements as it prepares for initial shipments later this year.
