Tianhesheng Isotopes Advances Boron-10 and Boron-11 Production for Semiconductor, Nuclear Power and Other Applications

Proprietary chemical-exchange distillation technology supports the production of nuclear-grade boron-10 enriched boric acid and electronic-grade boron-11 trifluoride

Tianjin Tianhesheng Advanced Material Technology Co., Ltd. (“Tianhesheng Isotopes”) has recently made progress in the industrialization of boron isotope materials. The company focuses on the research, development and production of enriched boron-10 and boron-11 materials. Its main products include nuclear-grade boron-10 enriched boric acid and electronic-grade boron-11 trifluoride, addressing material requirements in semiconductors, nuclear power and medical research. According to publicly available environmental impact assessment documents, its production facility in the Nangang Industrial Zone of the Tianjin Economic-Technological Development Area has a total design capacity of 15 metric tons of boron isotope products per year.

Boron Isotope Applications and Domestic Supply Development

Boron isotope materials include enriched boron-10, boron-11 and their compounds. They serve as important functional materials in semiconductor, nuclear power and pharmaceutical applications. Requirements for isotopic enrichment, chemical purity and impurity control vary by application.

Industrial-scale production technologies for high-purity enriched boron isotope materials have long been concentrated among companies in a small number of countries, leaving supply exposed to changes in international conditions. Tianhesheng Isotopes continues to develop proprietary processes to advance boron isotope production and domestic alternatives to imported materials.

Main Products: Boron-10 Enriched Boric Acid and Boron-11 Trifluoride

Established in October 2022 with registered capital of RMB 30 million, Tianhesheng Isotopes is headquartered at No. 18 Gangcang South Road, Nangang Industrial Zone, Tianjin Economic-Technological Development Area. The company focuses on two main product lines:

• Nuclear-grade boron-10 enriched boric acid: Boron-10 isotopic enrichment ≥99%, with a design capacity of approximately 10 metric tons per year, according to publicly available environmental impact assessment documents.

• Electronic-grade boron-11 trifluoride: Boron-11 isotopic enrichment ≥99.8%, with a design capacity of approximately 5 metric tons per year, according to the same documents.

These enrichment values refer to the proportion of the specified boron isotope. Chemical purity, impurity limits and delivery specifications are subject to the company’s product technical documentation.

Proprietary Chemical-Exchange Distillation for Continuous Boron Isotope Separation

Tianhesheng Isotopes uses an independently developed chemical-exchange distillation process for boron isotope separation and continuous production. The technology has been granted a Chinese invention patent, CN116688756B, titled “A Process Method for Continuous Production through Boron Isotope Separation.”

Building on this separation technology, the company continues to develop proprietary, standardized production of boron-10 and boron-11 materials to support downstream applications.

Semiconductor, Nuclear Power and Medical Research Applications

The company’s products and R&D activities target semiconductor ion implantation, nuclear reactor control materials, pharmaceutical intermediates for boron neutron capture therapy (BNCT), and quantum computing research. Medical-related applications concern pharmaceutical intermediates and research uses, with suitability determined by product specifications and downstream requirements.

The company has established collaborations with domestic enterprises and works with Tianjin University, Harbin Engineering University, Hunan University and Hebei University of Technology to connect boron isotope materials research with practical applications.

Company Recognitions and Compliant Supply

Tianhesheng Isotopes has received recognitions including High and New Technology Enterprise, Innovative SME, Science and Technology SME, and Tianjin Eagle Enterprise.

In June 2025, company co-founder Li Shenghui was interviewed for the Tianjin Economic-Technological Development Area’s official “Tongxin Talent Talks” series. In May 2026, industry media outlet “芯片揭秘” published an in-depth feature on the company.

Tianhesheng Isotopes states that it will continue developing and industrializing boron isotope materials, including nuclear-grade boron-10 enriched boric acid and electronic-grade boron-11 trifluoride. The company is committed to complying with applicable dual-use export control laws and regulations and providing reliable, compliant material supply for semiconductor, nuclear power and medical research applications.
