Abstract The accumulated heat energy of a heat-storage material is typically released over time. If a heat-storage material could preserve its accumulated heat energy for a prolonged period, the applicability of such materials would be expanded greatly. Herein we report a newly fabricated heat-storage material that can store latent heat energy for a long period and release the heat energy upon demand by applying an extremely low pressure. This material is a block-type lambda trititanium pentoxide (block-type λ-Ti3O5). The block-type λ-phase accumulates a large heat energy of 237 kJ L−1 and exhibits a pressure-induced phase transition to beta trititanium pentoxide. The pressure-induced phase transition occurs by applying only several tens of bars, and half of the fraction transforms by 7 MPa (70 bar). Such a low-pressure-responsive heat-storage ceramic is effective to reuse excessive heat in automobiles or waste heat at industrial factories.

The article presents the results of a study of the thermal properties of heat-accumulating materials based on bitumen paraffin. Heat-accumulating materials of a phase transition with a given melting point and phase transition obtained by mixing commercial solid bitumen paraffin and liquid paraffin and by mixing individual n-alkanes of a neighboring series were considered. It is shown that the sum of the enthalpies of melting and phase transition in the crystalline state thermal storage materials based on meta moderation depends on the width of the fractional part of the heat storage materials and cleanliness of the content of n-alkanes, from the fractional part of the heat storage material and the number of odd and even n-alkanes and their correlation, with the same melting point.
