Patent ID: 8370084

Claim:
A method for estimating a physical property of a ceramic, the method comprising: a step in which a computer calculates a Larson-Miller parameter from a time for which and a temperature at which the ceramic is heated; a step in which the computer acquires a porosity of the ceramic corresponding to the calculated Larson-Miller parameter, based on the calculated Larson-Miller parameter and a diagram correlating the Larson-Miller parameter and the porosity that is determined on the basis of an image obtained using a scanning electron microscope from samples having the same composition as the ceramic, the diagram being stored in a memory of the computer; and a step in which the computer acquires the physical property of the ceramic corresponding to the acquired porosity, based on the acquired porosity and a diagram correlating the porosity and the physical property obtained from samples having the same composition as the ceramic, the diagram being stored in a memory of the computer.
