摘要：

Samples based on liquid radioactive waste (LRW) and basalt with a weight content of LRW up to 30% are synthesized at temperatures of 1200 - 1400degreesC. The obtained materials, in addition to the vitreous phase, contain crystalline phases (clinopyroxene of the aegirite-hedenbergite composition and spinel). The glass materials synthesized from basalt and radioactive slag contain gehlenite and silicophosphates, and as the basalt content increases. augite (aegirite-hedenbergite) is synthesized as well. Crystalline phases capable of including radionuclides are formed in the synthesized materials. which decreases their leaching rate.
