    Ammonium fluoride-activated synthesis of cubic δ-TaN nanoparticles at low temperatures

    Cubic delta-tantalum nitride (δ-TaN) nanoparticles were selectively prepared using a K2TaF7 + (5 + k) NaN3 + k NH4F reactive mixture (k being the number of moles of NH4F) via a combustion process under a nitrogen...

    Columnar grain growth of yttria-stabilized-zirconia in inductively coupled plasma spraying

    Yttria-stabilized-zirconia (YSZ) was deposited 7 mm thick by inductively coupled plasma spraying (ICP) and a theory of nucleation and solidification of YSZ was introduced. The concentration was homogeneous wit...

    A study of the microstructure of yttria-stabilized zirconia deposited by inductively coupled plasma spraying

    Zirconia stabilized with 20 wt.% yttria was deposited to a thick free-standing type, ∼7 mm, by (inductively coupled plasma spraying) (ICPS). The spheroidization of particles and the microstructure of deposits ...
