A Method of Flexural Strength Measurement for Ceramics and High Temperature Flexural Strength of Alumina, Mullite

For applying ceramics to engine parts, a method to measure flexural strength of ceramics was studied. Alumina and mullite were evaluated in flexural strength at high temperature. The ring flexural test method was proposed to obtain flexural strength simply and the results were compared with the ones obtained from the three point bending measurement. It was discussed also to have the influence of r…
