AB - Mullite is considered a promising candidate for ceramic recuperators in turbo propelled engines, due to due to its low thermal conductivity, adequate thermal shock resistance, low cost, low density, thermodynamic stability, and reasonable strength at high temperatures. Unfortunately, the limited fracture toughness of mullite (∼1.8-2.8 MPa m1/2) is considered too low. Improving the fracture toughness to 4.7 MPa m1/2 is possible by the addition of ceria stabilised zirconia (CSZ). However, the addition of CSZ to mullite may also affect other properties. In this paper the effect of the addition of CSZ on the creep resistance is described by comparing a mullite-zirconia composite made with a commercially available mullite powder against the creep behaviour of mullite made from the same mullite powder. The stress exponent is close to 1 and the activation energies for creep were similar at 426±38 kJ mol-1 and 452±15 kJ mol-1. However, the resistance to creep as expressed by a given strain rate for a given stress is 250°C lower in the 20 vol% zirconia-mullite composite compared to the baseline.
