A new uniaxial compression test, developed for high strength ceramics, has successfully measured the strength of 94% alumina (Al2O3). Testing was done using a procedure developed specifically for obtaining strengths to 10 GPa on very difficult to machine ceramics. Strain gage analysis and fractographic observations confirmed that a uniaxial compressive stress state existed. Two existing test methods were also employed to measure the compressive strength of the alumina. Results from these tests are compared with the new methodology.
