    摘要: 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.

    摘要: This invention comprises a method of synthesizing ternary phosphide compos of the general formula M(II)M(IV)P.sub.2 by fused salt electrolysis in which a melt powder mixture containing phosphorus compounds is introduced into an electrolytic apparatus containing a liquid group II metal cathode and a group IV metal or semiconductor source. Electrolysis occurs under controlled conditions in which oxygen is excluded as an impurity to produce the desired ternary phosphide compounds.

    摘要: A process for producing monoclinic celsian comprising the steps of forming a mixture of an alkoxide of silica, an alkoxide of aluminum, and a salt of barium; adding a catalyst of a fluorine containing compound to the mixture; calcining the catalyzed mixture; and, heat treating the calcined mixture. This process uses a sol-gel process to progressively increase the amount of monoclinic phase in relation to the hexagonal celsian. Additionally, a process for producing monoclinic strontium aluminosilicate is disclosed.
