| Abstract: | A variety of Si-C-Al-N-(O) ceramics with different AlN and SiC contents were prepared by pyrolysis of Si-Al-C-O precursors at 1700°C in nitrogen. In those ceramics containing small amounts of aluminum, a new 27Al MAS NMR peak at 134.3 ppm was found. The existence of this peak is discussed in relation to recent findings in aluminum-containing complex ceramic systems. |
