| titleOfInvention | A kind of preparation method of fluor-apatite ceramic solidification body |
| abstract | The invention discloses a kind of preparation method of fluor-apatite ceramic solidification body, it is characterized in that：By calcium pyrophosphate 23～76%, calcium fluoride 8～26%, Disamarium trioxide（Or europium oxide, Gadolinia.）0.02～52%, sodium carbonate 0～15%, the component of silicon dioxide 0～16% and percent mass ratio take each component raw material, mix to obtain compound；The steps such as the ground drying of compound, pelletize, molding, dumping, vacuum heating-press sintering, prepared fluor-apatite ceramic solidification body.Using the present invention, can not only phosphorus in recycling high-level waste, can also solve the problems, such as that phosphorus and time actinium series nucleic dissolubility in glass solidified body are relatively low；The fluor-apatite ceramic solidification body of present invention preparation has excellent geological stability, irradiation stability, mechanical stability, chemical stability and heat stability, can be used as a kind of ceramic solidification body of the secondary actinium series high-level waste that safe handling toxicity is big, long half time, radioactivity are strong. |
