Abstract
Metal ternary sulfides of the general formula MM'.sub.2 S.sub.4 are synthesized by introducing stoichiometric amounts of nitrate precursors in concentrated nitric acid and heating to approximate dryness to yield a homogeneous powder mixture. The mixture is then exposed to a gaseous H.sub.2 S atmosphere under controlled conditions to produce the desired sulfide.
