A powder synthesis method was developed for preparing a highly sinterable submicrometer-sized sulfide from calcium and lanthanum alkoxides. Simultaneous sulfidization of these metal alkoxides at 400 to 750 Β°C in a pure H2S atmosphere produced stoichiometric CaLa2S4 powders with particle sizes in the
