The invention relates to the technical field of phase-change heat storage materials and provides a method for packaging a high-temperature molten salt particle phase-change material by utilizing inorganic glass powder. The method comprises the following steps of by adopting the inorganic glass powder as a packaging material, performing coating and packaging on molten salt particles, and then performing composite pressing on a product with a ceramic matrix to prepare a molten salt-ceramic phase-change heat storage material. In the method, by utilizing inorganic glass powder to perform microcapsule packaging on the molten salt particles, then composite sintering is performed on the packaged molten salt particles and the ceramic matrix material, and through packaging of the molten salt particles and mixed pressing of the packaged molten salt particles and the matrix material, melt molding of the inorganic glass powder exert the dampproof effect and can also provide the adhesion effect toa structural material. The high-temperature molten salt particle phase-change material by utilizing inorganic glass powder is simple in preparation method, relatively low in cost and liable in large-scale production, solves the problems of strong hygroscopicity and weak high-temperature structure strength and has an important significance of expanding a use environment of the high-temperature molten salt particle phase-change materials.
