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 27 Al 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.
