A porous sintered body suitable as an electroosmotic material constituting an electroosmotic flow pump is produced. At least one of BaO, SrO, CaO, TiO 2 , ZrO 2 , Na 2 O, and K 2 O is added to 100 parts by weight of fused quartz or fused silicic acid (base material SiO 2 ). 0.05 to a total of at least one of seeds or natural minerals containing aluminum silicate (alkali feldspar, kaolinite, feldspar, etc.), BaSiO 3 , BaTiO 3 , BaZrO 3 , SrSiO 3 , SiC Add 10 parts by weight. The base material may be SiO 2 —Al 2 O 3 in which fused alumina is added to fused quartz or fused silicic acid. [Selection] Figure 1 |
