Production of nuclear grade zirconium: A review
Zirconium and hafnium occur most commonly in nature as the mineral zircon (ZrSiO4) and less commonly as baddeleyite (ZrO 2). In general, the commercial nuclear grade zirconium production route involves ore cracking, Hf separation, calcination, pure chlorination and reduction to the pure metal.

Detrital Zircon U‐Pb Geochronology: Current Methods and
Detrital zircon geochronology is rapidly evolving into a very powerful tool for determining the provenance and maximum depositional age of clastic strata. This rapid evolution is being driven by the increased availability of ion probes and laser ablation inductively coupled plasma (ICP) mass spectrometers, which are able to generate agesAnnual Review of Earth and Planetary Sciences 37, 479–505. ), and is also likely to outperform the “traditional” interpretations. In this context, the main advantage of our approach compared to an analytical equivalent is merely the ability to specify numerically an arbitrary f(t r) derived from a physics-based model.A stochastic sampling approach to zircon eruption age

Detrital zircon U–Pb geochronology of a Cenozoic foreland
The U–Pb ages of the detrital zircon within the Lower Yinkiong Formation are older than late Palaeozoic, with a cratonic and early Himalayan Thrust Belt affinity, whereas the Cenozoic grains in the Upper Yinkiong Formation indicate a Himalayan Thrust Belt source and possibly a granitic body within the Asian plate.The two models have first been trained using a large trace-element data set of magmatic zircon and then validated on unseen data set during the training process. The performance of both models was evaluated using a fivefold cross-validation technique, which demonstrates that the models provide consistent results and yield good classificationApplication of Machine Learning to Wiley Online Library

Corrosion of Zirconium Alloys Used for Nuclear Fuel Cladding
The zirconium-tin system first yielded Zircaloy-1 (Zr–1.5% Sn), which performed reasonably well but which was much improved upon by an accidental contamination of a melt by stainless steel, yielding an approximate composition of Zr–1.5% Sn, 0.14% Fe, 0.10% Cr, 0.06% Ni. This alloy was dubbed Zircaloy-2 ( 3 ).
