以黄磷渣及硫酸钠-氯化钠（Na2SO4-NaCl）为原料，采用混合烧结法制备了高温复合相变储能材料（C-PCMs），并采用X射线衍射、扫描电镜、热重分析等手段分析了C-PCMs的化学相容性、力学特性、相变特性及热稳定性。结果表明：相变材料Na2SO4-NaCl在高温环境下对黄磷渣的侵蚀作用较小，两者具有良好的化学相容性；随着Na2SO4-NaCl掺量的增加，C-PCMs的结构趋于致密，力学强度及潜热值逐渐增大；当相变材料Na2SO4-NaCl掺量超过60%（质量分数）时，C-PCMs出现明显的泄漏现象；当相变材料Na2SO4-NaCl掺量为60%（质量分数）时，C-PCMs的抗压强度、维氏硬度、密度和潜热值分别为122.30 MPa、208.90 HV、2.08 g/cm3和119.09 J/g，经120次热循环，C-PCMs中的Na2SO4-NaCl没有发生泄漏，相变特性也保持良好。

The high temperature composite phase change energy storage materials（C-PCMs） were prepared by mixed sintering method using yellow phosphorus slag and Na2SO4-NaCl as raw materials.The chemical compatibility，mechanical properties，phase change characteristics and thermal stability of C-PCMs were analyzed by XRD，SEM and TG-DSC.The results showed that the phase change material Na2SO4-NaCl had less erosive effect on yellow phosphorus slag under high temperature environment，and both had good chemical compatibility.With the increase of Na2SO4-NaCl content，the structure of C-PCMs was tended to be densified，and the mechanical strength and latent heat value were gradually increased.When the content of phase change material Na2SO4-NaCl was exceeded 60%（mass fraction），the C-PCMs had obvious leakage phenomenon.When the content of phase change material Na2SO4-NaCl was 60%（mass fraction），the compressive strength，Vickers hardness，bulk density and latent heat of C-PCMs were 122.30 MPa，208.90 HV，2.08 g/cm3 and 119.09 J/g，respectively.After 120 thermal cycles，the Na2SO4-NaCl in the C-PCMs did not leak，and the phase change properties remained good.
