Sialon, which is one of promising materials in the field of engineering ceramics, is prepared by mixing a silicon nitride precursor such as amino- or imino-silanes and an alumina precursor such as trialkoxy- or triacyloxy-aluminums or polyaluminoxanes to obtain a sialon precursor, and then heating the sialon precursor at a temperature of not lower than 1000 DEG C. either in an ammonium or inert gas atmosphere or under reduced pressures.
