TECHNOLOGY LICENSING OPPORTUNITY: Compact Modular Furnace

The Compact Modular Furnace from Los Alamos National Laboratory gives researchers a practical way to perform extreme-temperature testing of molten salts and metals in a glovebox-compatible, tightly controlled environment. By combining a small footprint, interchangeable components, optical access, and the ability to isolate heat directly at the sample, it enables safer and more flexible experiments that would normally require much larger, more expensive equipment. The furnace design supports rapid setup for a range of materials studies, including contact angle measurement, compatibility testing, and thermal cycling, while helping teams work with highly reactive substances without exposing them to air or moisture. The result is a versatile platform that expands what can be studied, shortens experimental turnaround, and brings high-performance thermal testing into a form that is easier to deploy and use. The furnace can be heated using resistive heating elements to reach up to 750°C in vacuum or inductive heating elements to melt high temperature samples such as refractory metals.

The Challenge:

This invention addresses the difficulty of studying highly reactive materials under extreme heat while keeping them isolated from air and moisture. The Compact Modular Furnace provides a way to run controlled experiments on molten salts and metals in a compact setup that can fit inside a glovebox, which is important because these materials can be unsafe or unusable in ordinary open-air equipment. The furnace system can be isolated from the glovebox atmosphere to allow introduction of process gases, high vacuum, or to prevent fumes from contaminating the glovebox environment. It also allows researchers to observe the sample during testing, so they can measure behavior such as wetting, compatibility and thermal response without interrupting the experiment or exposing the material to the environment. By combining a small footprint, adaptable parts and a design that concentrates heat where it is needed, the system reduces the need for large, specialized furnaces and makes advanced testing more practical, flexible, and efficient.

Problems Solved:

The Compact Modular Furnace solves the problem of having to choose between precise high-temperature testing and a controlled, contamination-free environment. It gives researchers a way to heat and observe sensitive materials without exposing them to air, moisture, or other conditions that can distort results or damage the sample. It also addresses the limitations of large, inflexible furnaces by offering a smaller, easier-to-configure setup that can be adapted for different experiments and measurement tools. Protecting sensitive equipment such as cameras and spectrometers from extreme heat conditions. In practice, that means scientists can study molten salts and metals more safely, with less equipment costs, and with better access to the kinds of measurements needed to understand how these materials behave under extreme conditions.
