| Popis: | Borobasalt systems were studied as host materials for incorporation of radioactive waste from pyroelectrochemical technology. For all the examined compositions, the leach rates are of the order of 10–7 g cm–2 day–1, which is quite acceptable for radionuclide immobilization. The synthesis temperature ensuring formation of homogeneous glasses is about 1250°С for all the examined compositions. The host material is capable to incorporate up to 40 wt % phosphate wastes, which seems quite sufficient from the viewpoint of technology. The system is only weakly sensitive to variations of the boric anhydride content. |
