A sintered silicon carbide product having improved fracture toughness contains from 1% to 80% by weight of (a) a uniformly dispersed, nonagglomerated, high metal content silicide of iron, nickel, cobalt or molybdenum in which the metal/silicon ratio is equal to or greater than 1. The silicon carbide starting material can be alpha-phase, beta-phase or a mixture of the two. |
