The creep behaviour of silicon nitride with three different sintering aids has been studied. In addition to creep rates, the stress exponents and activation energies have been determined. The creep resistance has been related to the strength, fracture toughness and grain character (size and aspect ratio), as well as the liquid-phase content and its high-temperature refractoriness. The mechanisms of creep in the silicon nitrides are discussed.
