The indices of long-time strength (time and strain to rupture) of densely sintered oxide ceramic in the temperature interval 1400 – 1600 °C under loads to 60 MPa are determined. The characteristics of creep and creep rupture are interrelated: irrespective of the size of the crystals in the ceramic and the testing conditions the product of the steady creep rate and the time to rupture is a constant, i.e., the strain to rupture is a constant. Therefore, the service life of materials can be determined from measurements of the creep rate.
