Abstract

Phase change material (PCM), which enables heat storage based on phase transition, plays an important role for efficient energy utilization. This paper briefly describes our recent study about all-solid PCM by combination of vanadium dioxide (VO₂) with latent heat storage capacity and multicomponent glass, i.e., VO₂-dispersed glass. A B₂O₃-P₂O₅-V₂O₅ glass system is used as a matrix for the VO₂-dispersed glass. An attempt to describe its latent heat storage function is given. Endothermic behavior due to structural phase transition of the VO₂ crystals was observed in the VO₂-dispersed sample, and the transition enthalpy corresponding to latent heat storage capacity was estimated to be ΔH~9.5 J/g. The value of the studied sample was larger than the value of dispersed glass in the BaO-TeO₂-V₂O₅ system that was previously reported. Potential for PCM was considered in the studied sample.
