This paper studies the experimental conditions, composition, trace element content and Lu-Hf isotopic ratios in synthetic zircons. The authors used zirconia and lithium silicate as raw material and lithium molybdate and molybdenum oxide as flux, added such elements as Hf, Lu, Yb, U, Th, and Pb, and then transferred to the platinum crucible with lid after full mixing. The results show that values of U, Th, Pb and some other trace elements vary remarkably from one crystal to another and also from core to rim in one crystal. The result suggests that synthetic minerals may prove useful as in situ method development tools and can provide thinking and means for the production of other synthetic minerals as isotopic reference materials for in situ isotopic studies.
