WASHINGTON, March 27, 2025 (GLOBE NEWSWIRE) -- ASP Isotopes Inc. NASDAQ: ASPI (\"ASP Isotopes” or the “Company”), an advanced materials company dedicated to the development of technology and processes for the production of isotopes for use in multiple industries, today announced that it has started commercial production of enriched Silicon-28 at its second Aerodynamic Separation Process (ASP) enrichment facility in Pretoria, South Africa. Many researchers believe that highly enriched Silicon-28 will be required by manufacturers of next-generation semiconductors. Naturally occurring Silicon has three isotopes – 28, 29 and 30. The 29 isotope has a ½ positive spin, which is an intrinsic form of angular momentum carried by elementary particles. In contrast, highly enriched Silicon-28 is spin-free where qubits are protected from sources of decoherence that causes loss of quantum information(1). In addition to its potential to process superior information such as qubits, it is believed that highly enriched Silicon-28 can conduct heat 150% more efficiently(2) than natural Silicon, which will potentially allow for chips to become smaller, faster and cooler. ASP Isotopes’ proprietary technology can enrich isotopes of low atomic mass (such as silane (SiH4), molecular mass of 32), as well as isotopes of heavier masses. Other companies developing methods to enrich silicon generally either enrich silicon tetrafluoride (SiF4) or a halo silane. Neither of these chemicals can be used directly by a semiconductor company and require chemical converting processes that potentially harm the purity of the final product. By processing silane directly, the Company believes that its finished product will be a higher quality and may be used by semiconductor companies without the need for additional chemical conversion processes. “To create faster, smaller next-generation semiconductors, the world is likely going to...
