摘要
Aluminum borate microtubes were prepared in excellent yield by annealing the Al2O3-NaBH4-NiCl2 starting materials at 1050 °C under N2(H2) atmosphere. The tubes are usually open at each end with the outer diameters narrowly distributed at ca. 1 μm. XRD results and TEM analysis identified the composition of these tubes as single-crystal orthorhombic Al18B4O33. These newly discovered ceramic microtubes with open ends have a variety of promising applications such as being filled with other materials for protection or for the fabrication of novel composites or filtering media.
