The addition of various compounds to LaB/sub 6/ did not improve the thermionic emission over that of pure LaB/sub 6/. This experience and general conclusions, which result by considering the vaporization properties of these and other materials, greatly limit the options available to improve the properties of LaB/sub 6/ by forming a ternary system. The principles which must be considered, in order to simplify future work, are described. 10 references, 7 figures, 6 tables.
