Abstract: Low melting point alloys are potential phase change thermal storage materials and heat transfer agent due to its excellent property such as high thermal conductivity coefficient, high thermal storage density, excellent thermal stability, low melting point and high boiling point. This paper review the phase change thermal storage low melting point alloys based on its thermo-physical properties such as phase change temperature, phase change latent, coefficient of thermal conductivity and stabilization. The steam pressure, interfacial force, viscosity and capacity of heat are introduced to explore the application of low melting point alloy in heat transfer materials. The high temperature corrosion behaviors of low melting point alloy are also introduced. And finally, the future work about the thermal storage and heat transfer low melting point alloys are prospected.

Key words: low melting point alloy, heat transfer, thermal storage, corrosion
