Abstract：The mixed sintering method was used to shape the ternary chlorine salt system NaCl-KCl-MgCl2 with magnesium oxide ceramic matrix.The influence of pressing pressure,sintering temperature and salt content on the material molding were studied and the heat storage performance was tested.The experimental results show that when the preparation conditions are the 50 ％ salt content,sintering temperature of 450 ℃ and 8 MPa pressing pressure,the preparation effect is better.At that time the phase change material is no seepage,the composite material has a smaller volume change and a higher density.The DSC test results show that the phase transition temperature of composite phase change heat storage material is 399.8 ℃,and the phase change latent heat is 129.6 J/g.
