普通人造岩石固化体可以很好地包容从后处理厂产生的高水平放射性废液，但对钠离子的包容效果一直不好。研究表明，含Ｎａ２Ａｌ２Ｔｉ６Ｏ１６型黑钛铁钠矿的人造岩石固化体可以用来包容高钠高放废液。所制备的含废物氧化物质量分数１１．５％、Ｎａ２Ｏ５．０％的人造岩石固化体具有很好的物理稳定性、化学稳定性和对不同废物包容量的适应能力。人造岩石固化体通常只能包容２％～３％的Ｎａ２Ｏ，因此，本工作较大地提高了人造岩石固化体对高钠高放废液的包容能力。 Ordinary artificial rock solidified body can well tolerate the high level of radioactive waste liquid generated from the reprocessing plant, but the sodium ion tolerance has not been good. Studies have shown that artificial rock solidified bodies containing NaAl2Ti6O16 black ilmenite ore can be used to contain high-sodium high-level liquid waste. The prepared rock solidified body containing 11.5% of the mass fraction of oxides of the waste, Na2O5.0% has good physical stability, chemical stability and adaptability to different waste package capacity. Artificial rock solidified body usually contain only 2% ~ 3% of Na2O, therefore, this work has greatly increased the rock solidified body of high sodium high capacity waste containment capacity.
