What We Do

At Arbor Halides, we combine decades of molten salt expertise with a practical, hands-on approach to solving real-world challenges. From synthesizing and purifying salts to instrumenting and operating large-scale facilities, our deep knowledge of molten salts enables us to deliver the top-quality materials researchers need—reliably and at scale.

The Arbor Halides Difference

Actinide Halides: Fueling the Next Generation of Reactors

Actinides like uranium and thorium can power nuclear reactors. In molten salt reactors (MSRs), these elements are used in the form of chlorides and fluorides (aka salts). The scientific name for these uranium and thorium salts is “actinide halides”. At Arbor Halides, we specialize in the synthesis and purification of these complex salts, ensuring they meet the rigorous standards required for cutting-edge nuclear research and development. By providing a large negative coefficient of reactivity, these halides keep MSRs inherently stable even as temperatures rise, reducing reactivity and preventing runaway heating.

Advanced Purification for Low Moisture & Oxygen

Moisture and oxygen are among the most critical impurities in molten salts, leading to corrosion and other undesirable effects. Many suppliers overlook these factors; at Arbor Halides, minimizing these impurities is our specialty. We use advanced purification techniques to ensure consistently low levels of moisture and oxygen. More importantly, we specify moisture and oxygen levels in detail, allowing researchers to select precisely the purity they require.

As a veteran-owned company, we stand behind the quality of every shipment, ensuring reliability from shelf to application. When you choose Arbor Halides, you’re choosing a trusted partner with a dedication to quality, integrity, and the continued growth of American business.

Applications

Molten Salt Reactors (MSRs)

As the energy landscape shifts toward cleaner technologies, Molten Salt Reactors (MSRs) are emerging as a key solution for the future of nuclear energy. With the ability to operate at high temperatures and low pressures, MSRs significantly reduce the traditional safety concerns of water-based reactor designs while improving efficiency. By integrating fuel directly into the salt, MSRs achieve higher burnups, extracting more energy from the fuel while minimizing waste. At Arbor Halides, we’re excited to be part of this evolution, supplying the actinide salts that power MSRs and help establish them as a cornerstone of the global transition to sustainable, clean energy.

Nuclear Fuel Recycling

Nuclear fuel recycling is a critical step toward making nuclear energy more sustainable. Spent nuclear fuel contains over 90% uranium, a resource that can be reused. Molten salts play a vital role in the high-temperature recycling process, sometimes called “pyroprocessing”. Compared to aqueous-based recycling methods used abroad, molten salt-based recycling methods offer several advantages: they have a smaller footprint, require less cooling time, and can be directly coupled to Molten Salt Reactors (MSRs), leading to less waste that needs to go in the ground. Although this method of fuel recycling has been extensively developed, it has yet to be implemented at a commercial scale. At Arbor Halides, we are committed to advancing these technologies, helping to solve the nuclear waste problem and paving the way for a more sustainable energy future.

Thermal Energy Storage

Molten salts play a vital role in energy storage. They can help renewable energy effectively integrate with the grid by storing excess power generated by solar and wind sources, smoothing out the supply fluctuations that naturally occur with renewables. As a result, clean energy remains available, even when the sun isn’t shining or the wind isn’t blowing.

Arbor Halides provides the chloride-based molten salts powering next-generation thermal storage systems. Our premium molten salts ensure efficient, corrosion-resistant thermal storage systems, helping make renewable energy more reliable and widespread.

Fusion Reactor Blankets

Fusion energy promises an abundant, clean power source, and molten salt blankets are key to making it a reality. These blankets manage the intense heat from fusion reactions while also breeding tritium, the critical fuel needed for sustained fusion. At Arbor Halides, we recognize the potential of molten salts in advancing next-generation clean energy, and we remain open to supporting fusion-focused projects as blanket technology continues to develop.

Advanced Materials & Electronics

In addition to energy applications, molten salts are being actively explored for uses in areas such as producing quantum dots for LEDs and silicon purification for computer chips. At Arbor Halides, we are proud to supply the high-quality molten salts that are integral to these emerging technologies.
