Rezumat:

The aim of this paper is to report the results of a systematic high-resolution transmission electron microscopy study on Al18B4O33. The fluxing agent method permits the formation of needle-shaped whiskers of Al18B4O33, having sub-micron thickness with a tendency to come and fuse together. Amounts of 25% and 50% K2SO4, K2CO3 or KCl were used liked fluxing agents. Using this method, the optimum temperature for the synthesised compound was found to be 1000°C. The investigation techniques were X-ray diffraction and electron microscopy.
