METHOD OF IMMOBILISING LIQUID HIGHLY RADIOACTIVE WASTES INTO GLASS CERAMIC Russian patent published in 2013 - IPC G21F9/16

Abstract RU 2494483 C1

FIELD: chemistry.

SUBSTANCE: method of immobilising highly radioactive wastes into a porous glass ceramic matrix obtained by foaming molten recycled lamp glass. Immobilisation and fixation of radionuclides in the porous glass ceramic is carried out by performing the following processes: impregnating the glass ceramic, saturating, drying, heating with distillation of gaseous products, calcination at 1000°C.

EFFECT: invention enables to use a readily available, cheap sorbent with high open porosity.
