Using a low temperature, organic-free hydrothermal technique, single-crystalline barium polyborate Ba 3 B 6 O 9 (OH) 6 (BBOH) nanorods were synthesized. It was found that b-BaB 2 O 4 (BBO) nanospindles can be achieved by annealing the BBOH nanorods at a relatively low temperature of 810 C. Transmission electron microscopy (TEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) techniques were used to characterize these nanomaterials. The formation mechanisms are discussed in
