ASP Isotopes Inc. Enters Into Purchase Agreement With a Leading Semiconductor Company for the Supply of Highly Enriched Electronic Gases

- Purchase agreement covers supply of highly enriched silicon-28, which is expected to be supplied in 2024.

-ASP Isotopes Inc. is in discussions with multiple semiconductor manufacturers regarding the supply of highly enriched isotopically pure electronic gases for next-generation semiconductors, anticipated to enable technologies such as quantum computing and artificial intelligence.

WASHINGTON, April 01, 2024 (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 entered into a purchase agreement with an industry leader in the design and manufacturing of semiconductors. Under the terms of the agreement, ASP Isotopes expects to supply highly enriched silicon-28 to the customer for use in next-generation semiconductors. The product is expected to be supplied from the Company’s South African production facility and shipped to the customer in the USA during 2024.

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. 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’s 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 require materials that are currently not available in commercial quantities,” said Paul Mann, ASP Isotopes’ Chairman and Chief Executive Officer. “ASP Isotopes is currently working on many isotopically pure elements that we believe will help semiconductor companies create the chips that the world will require in the future to enable technologies such as Quantum Computing and Artificial Intelligence.

ASPI’s South African multi-isotope production facility is expected to be capable of producing up to 10 Kgs of highly enriched silicon-28 per annum. To meet the anticipated demand later this decade, the Company anticipates constructing a larger production facility as part of the proposed Icelandic cluster, slated to start production during 2026. The Company expects to start the construction of its Icelandic facilities during 2024 with first production of medical isotopes expected in 2025. The Company is in discussions with many companies, both in the semiconductor industry as well as healthcare industries regarding their requirements for products that might be produced from the Icelandic cluster.

About ASP Isotopes Inc.

ASP Isotopes Inc. is a pre-commercial stage advanced materials company dedicated to the development of technology and processes to produce isotopes for use in multiple industries. The Company employs proprietary technology, the Aerodynamic Separation Process (“ASP technology”). The Company’s initial focus is on producing and commercializing highly enriched isotopes for the healthcare and technology industries. The Company also plans to enrich isotopes for the nuclear energy sector using Quantum Enrichment technology that the Company is developing. The Company has isotope enrichment facilities in Pretoria, South Africa, dedicated to the enrichment of isotopes of elements with a low atomic mass (light isotopes).

There is a growing demand for isotopes such as Silicon-28, which will enable quantum computing, and Molybdenum-100, Molybdenum-98, Zinc-68, Ytterbium-176, and Nickel-64 for new, emerging healthcare applications, as well as Chlorine-37, Lithium-6, and Uranium-235 for green energy applications. The ASP Technology (Aerodynamic Separation Process) is ideal for enriching low and heavy atomic mass molecules. For more information, please visit

Forward Looking Statements
