Young’s modulus and Poisson’s ratio of SiC ceramics at temperatures >1400°C were obtained using a laser ultrasonics method that included a Fabry‐Pérot interferometer (LUFP). At temperatures <1000°C, Young’s modulus and Poisson’s ratio measured using the LUFP method agreed well with those measured using standard contact methods, such as the resonance method and the ultrasonic pulse method. These results showed that the LUFP method is a powerful tool for measuring high‐temperature elastic properties of advanced ceramics in a noncontact manner.
