GLASS-FORMING BORON PHOSPHATE COMPOUND FOR IMMOBILIZATION OF ALUMINUM-CONTAINING LIQUID HIGH-RADIOACTIVE WASTES Russian patent published in 2005 - IPC

FIELD: processing of liquid A-wastes.

SUBSTANCE: the invention is pertaining to the field of processing of liquid A-wastes. The invention presents: a glass-forming boron phosphate compound for immobilization of the aluminum-containing liquid highly radioactive wastes by their vitrification. The compound contains: sodium oxide, aluminum oxide, boron oxide, phosphor oxide and natural impurities of oxides of multivalent chemical elements. At that it in addition contains lithium oxide at the following ratio of components (in mass %): Na₂O - 22.0-26.0;_{Al2O3 - 13.0-28.0;B2O3 - 3.0-6.0;P2O5 - 38.0-55.0;Li2O - 0.5-1.0; the oxides of multivalent chemical elements - the rest. Advantages of the invention consist in production of a qualitative homogeneous glass.}

EFFECT: the invention ensures production of a qualitative homogeneous glass.
