Abstract: B6O is a potential superhard material with a hardness of 45 GPa measured on single crystals. Recently it was found that different oxides can be utilized as an effective sintering additive which allows densification under low pressures. In this work the effect of addition of Y2O3/Al2O3 on high temperature properties was investigated using impulse excitation technique (IET), hardness measurements and dilatometric measurements. The IET technique reveals the softening of the residual B2O3 in the materials without additives at 450 degrees C; in the materials with Y2O3/Al2O3 the softening is observed at only about 800 degrees C. This data agrees with the values found for different borate glasses.
