There are 8.6%~10.91% foreign matter in the sphenes, in which radioactive elements of strontium, cesium and uranium range from 4.26% to 4.58%. The change of structural cell parameters of sphenes is still very little,Δa=-0.0009 nm~0.0041 nm,Δb=0.0018 nm~0.0004 nm,Δc=0.0002 nm~0.0048 nm,Δβ=-0.10°~0.09° with high crystallinity of 99.27%~96.46%. Though, the age of sphene from the Fenghuang Mountain is about 1000 Ma, and experienced 775 Ma~1758 Ma geological evolvement and alpha decay, its crystallinity only decreased 3%, and its crystal shape and structure are still fine, indicating that sphene is of good ability to solidify radioactive elements. Therefore, sphenes are ideal minerals for solidifying nucleus waste.
通过对北祁连牛心山变质杂岩体中榍石(775Ma)和山西凤凰山花岗岩中榍石(1758Ma)的XRD及EDS等测试与研究,结果表明:两地榍石的杂质元素质量分数高达8.6%~10.91%,放射性核素锶、铯和铀的质量分数达4.26%~4.58%;晶胞参数的变化极小,△a=-0.0009nm~0.0041nm、△b=0.0018nm~0.0004nm、△c=0.0002nm~-0.0048nm、△β=-0.10°~0.09°,结晶度仍高达99.27%~96.46%,榍石经过10×10^8a的地质作用,结晶度仅减少了3%,显示榍石固化放射性系列核素的能力较强,虽经历了约775Ma~1758Ma的复杂地质演化及其所含放射性核素的衰变作用,其晶体结构完好,稳定性极高,是值得期待的理想核废物固化矿物。
