%X The effect of Na2O on mechanical properties of MoSi2/oxide composites for heating elements was investigated. The results obtained show that the specimens with low Na2O content possess higher bending strength and Weibull modulus after heat treatment at 1773K for 100h. Furthermore, removed Na composites have better creep resistance and higher BDTT. Their creep strain rate is 2/5 and 1/3 or less than that of the unremoved Na composites at 1243K and 1303K, respectively, and their BDTT is increased 100K.
