摘要：

A novel single-crystalline microtubular structure of aluminum-rich mullite, Al2(Al2+2xSi2-2x)O10-δ (x-0.375) which has perfect rectangularly framed cross-section with specific crystallographic facets, a large hollow interior channel of 0.5-3 μm width, and thin walls (50-100 nm). The ceramic microtubes are mechanically hard with potential applications as hollow needles for drug delivery, microchannels for MEMS/biochips, and as optical resonance cavities and waveguides.
