摘要： The disclosure relates to a sintered aluminum nitride base composite material which consists essentially of 5-50 wt % of SiC whiskers, 0.5-10 wt % of sintering assistant(s) selected from SiO.sub.2, Y.sub.2 O.sub.3, CaO, Al.sub.2 O.sub.3, Mo, W, Mo.sub.2 C, WC and oxides of elements of the lanthanide series and the balance of AlN. By virtue of dispersion of SiC whiskers in AlN base ceramic matrix the sintered material is very enhanced in strength, toughness and hardness and exhibits increased heat conductivity. The sintered material provides excellent cutting tools since Rockwell superficial hardness, 45N scale, can be made higher than 85.
