Abstract

Nanoparticles and nanorods of CuSb₂O₆ are prepared by hydrothermal method and its high temperature α-phase is stabilized at room temperature. The average size of the nanoparticles is ca. 13.7 nm. The nanorods, with a width of ca. 20 nm and an aspect ratio of ca. 5, are the agglomerates composing of smaller nanoparticles with an average size of ca. 8.3 nm. Compared with the high temperature α-phase of bulk sample at 400 K, the lattice of nanophases elongated in ab plane and compressed along c direction. The CuSb₂O₆ nanoparticles exhibit predominant paramagnetic phenomenon. The difference in magnetic properties of the nanoparticles and nanorods indicates the interfacial interaction of agglomerated nanoparticles.
