These results evince the potential of EPCM in an optimized design for controlling exothermic reactions in a simple NINA. This level of temperature control is important to enable conformance to the ''sensitive'', ''specific'', and ''robust'' aspects of the ASSURED guidelines. Once the abundant heat from the CaO reaction begins to melt the EPCM, the additional heat produced by the exothermic reaction is converted into the latent heat of fusion of the EPCM. Thus, the temperature in the EPCM remains constant at the selected melting temperature until the solid to liquid transition is complete (provided heat transfer within the EPCM is rapid). Once the CaO reaction has reached equilibrium, the energy stored as latent heat keeps the two-phase EPCM at the target temperature until complete solidification.
