相變材料因其優越潛熱被廣泛應用于太陽能光熱技術中，絕大多數有機相變材料的導熱系數非常低，大多介于01～04 W·m-1·K-1之間。此外，相變材料流動性大，因此需采用導熱性能好、具有穩定結構的基體支撐有機相變材料，改善其應用性能。一些天然礦物具有適當的比熱與導熱系數、多孔道的微結構以及天然的熱穩定性與化學兼容性等礦物特性，被用于支撐相變材料制備太陽能儲熱材料。探討了礦物的結構特性與性能優勢，總結了石墨、珍珠巖、蛭石、硅藻土、埃洛石以及石膏等礦物基太陽能儲熱材料的制備研究。在此基礎上介紹了礦物基太陽能儲熱材料在太陽能建筑節能、太陽能熱水器、太陽能熱發電等太陽能光熱領域中的應用，并展望了礦物基太陽能儲熱材料的發展趨勢和應用前景。

The phase change materials (PCM) have been widely used in the fields of solar thermal technology due to their privileged latent heat. But the thermal conductivities of PCM are low and ranged of 01～04 W·m-1·K-1, also the PCM are form unstable. So the host materials with the high thermal conductivity and formstable are needed to support the PCM and enhanced their application performance. Some natural Mineral materials were selected as supports of phase change materials for solar thermal energy storage materials (STESM) due to their mineral characters: suitable specific heat and thermal conductivity, porous microstructure, natural thermal stability and chemical compatibility. This paper discusses the structural characters and performance advantages of the minerals, and reviews recent advances in the preparation of mineralbased STESM which from graphite, perlite, vermiculite, diatomite, halloysite and gypsum. And their applications in the fields of solar thermal are introduced: energy conservation in building, solar water heater and concentrating solar power; also the research direction and the future development tendency were pointed out.
