Summary

A floating zone (FZ) furnace was modified into a high vacuum type furnace in order to grow high-purity single crystals of MoSi2 and WSi2. The impurity levels of the grown MoSi2 single crystals were very low and the residual resistivity ratio was large, indicating that the grown crystals were of good quality. Compression tests of MoSi2 and WSi2 single crystals were conducted at 900°-1500°C, and the orientation and temperature dependence of the strength were investigated. Transmission electron microscopic observation of the deformed specimens was also conducted.
