Keywords： infiltration

A new type of high temperature energy storage material was obtained through the melt infiltration method,using compounding SiC ceramic foam as matrix and Na_2SO_4 as phase change material.The resulting composite material was measured by XRD,SEM,TG-DSC methods.The experimental re-sults indicate that the composite is composed of silicon carbide,sodium sulfate and square quartz,and no chemical reactions occurs between Na_2SO_4 and SiC matrix.Na_2SO_4 has a good bonding with the SiC ceramic foam matrix.As the composite material is characterized by high thermal energy storage den-sity and high thermal conductivity,it is suit for energy storage under high temperature.
