Spontaneous growth of the hexagonal ZrB2 nanoplates driven by the screw dislocation mechanism

Abstract

ZrB2 nanoplates had been successfully synthesized by a facile molten-salt assisted borothermal reduction technique at 1273 K with 10:1 mass ratio of salts/reactants for the first time. The as-synthesized nanoplates had the hexagonal shapes with the lateral size of 2 ~ 6 μm and the thickness of 50 ~ 200 nm. Observation of key features of helical fringes and herringbone contours confirmed the presence of the screw dislocations in the as-synthesized nanoplates. A novel screw dislocation growth mechanism was proposed to interpret the formation of the nanoplates. This work not only provides a new growth mechanism for ZrB2 nanoplates but also provides a new strategy for synthesizing ZrB2 nanoplates.
