A bend-test furnace is described for measuring the modulus of rupture on beryllium oxide at elevated temperatures. Test beams were subjected to three-point loading by utilizing a conventional lnstron tensile-testing machine. These tests were performed in a helium atmosphere at temperatures ranging from 75 to 3000 deg F. Comparative data are presented for hot-pressed, cold-pressed, and slip-cast specimens supplied by several manufacturers. Preliminary results indicated that, in general, the hot-pressed specimens have the highest modulus at all temperatures which were investigated.
