The Structure, Property, and Ion Irradiation Effects of Pyrochlores: A Comprehensive Review
Crystals, 2023 Since the beginning of the use of nuclear energy, humans have been faced with the problem of radionuclide disposal. At present, a large amount of waste is stored in pools or dry tanks at reactor sites. With the development of the nuclear power generation

Trace element partitioning between pyrochlore, microlite, fersmite and silicate melts
Geochemical Transactions, 2020 We present experimentally determined trace element partition coefficients (D) between pyrochlore-group minerals (Ca2(Nb,Ta)2O6(O,F)), Ca fersmite (CaNb2O6), and silicate melts.

Exploiting periodic first-principles calculations in NMR spectroscopy of disordered solids [PDF]
, 2013 Much of the information contained within solid-state nuclear magnetic resonance (NMR) spectra remains unexploited because of the challenges in obtaining high-resolution spectra and the difficulty in assigning those spectra.

Phase formation on the surface of lead ferroniobate depending on the conditions of mechanochemical synthesis and sintering [PDF]
Science of Sintering, 2016 The perovskite structure is formed at lower temperatures with an increase in the time of preliminary activation. It is demonstrated that thermal treatment of mechanically activated for 25 minutes mixture composed of niobium oxide, lithium ...
