Basalt-based glass materials for immobilization of medium-active waste

At temperatures of 1200 - 1400 ° C, samples were synthesized from liquid radioactive waste (LRW) and basalt with a mass content of LRW oxides up to 30%. The obtained glass materials, along with the glass phase, contain crystalline phases (clinopyroxene of aegirine-hedenbergite composition and spinel). Glass materials synthesized from basalt and radioactive slag contain gelenite and silicophosphates, and with an increase in the basalt content in the samples, augite (aegirine-hedenbergite) also crystallizes. Crystalline phases are formed in the synthesized materials, capable of including radionuclides, which leads to a decrease in the rate of their leaching. Il. 4, bibliography: 8 titles.
