The invention discloses a method for manufacturing a solid-phase converter by glass beads. The method comprises the concrete steps of taking glass beads with the grain diameters being 150 to 200 meshes, 200 to 250 meshes and 250 to 300 meshes; respectively pouring the glass bead into a sodium silicate saturated solution; after full stirring, fishing, drying and sieving the glass beads; preparing the dried glass beads according to the required parts; performing full and uniform mixing; putting the uniformly mixed glass beads into a mold; controlling the pressure to be 1.5 to 3mN/mm<2>; performing compaction; covering a mold cover; putting the mold into a resistance furnace to be heated to 680 to 750 DEG C; performing heat insulation for 8 to 15min; taking out the mold; performing cooling and demolding; obtaining the solid-phase converter. The solid-phase converter prepared by the method has the expansion coefficient matched with the liquid ring phase; the porosity can be obtained by regulating the proportion according to requirements; the blank of manufacturing the high-performance solid-phase converter in batch by the glass beads is filled.
