Abstract: This study aims to identify an inorganic metallic substance that undergoes a solid-solid phase transition at room temperature. Some crystal structures undergo phase changes where they absorb and/or release heat depending on the surrounding conditions. This work focuses on a zinc-manganese alloy that undergoes a martensitic phase transition between the epsilon and alpha phases. The first successful sample underwent an exothermic reaction between 550 and 600 degrees Celsius. While crystal growth was observed, optimization is ongoing. Minimizing the temperature at which the phase transition occurs will be necessary for residential and commercial applications. Expected applications include enhancing thermal storage properties in concrete walls and spray foam insulation. The thermal properties will help regulate indoor temperature and contribute to the overall efficiency of the buildings in which it is used.
