 Title    Zum System Ca/Mo/O: Phasendiagramm, Synthese und Charakterisierung der ternären Verbindungen On the System Ca/Mo/O: Phase Diagram, Synthesis and Characterization of Ternary Compounds  
 Abstract    The phase diagram of the ternary system Ca/Mo/O has been determined. Powder samples of the ternary compounds CaM o04, CaM o03, CaMo50 8, Ca16 5Mo,3 5O40 and Ca5 45Moi80 32 were prepared by solid state reactions. Rietveld analysis based on powder X-ray diffraction data shows that the compound CaMo50 8 has monoclinic structure (P2,/c) with a = 7.549, b = 9.064, c = 9.974 A, 3 = 110.04°. CaMo.O*, Ca I*. <Moit sOjo and Ca« 4sMoieO-i9 are semiconductors over the temperature range 75 to 300 K.

 Title    Zum System Sr/Mo/O: Phasendiagramm, Synthese und Charakterisierung der ternären Verbindungen On the System Sr/Mo/O: Phase Diagram, Synthesis and Characterization of Ternary Compounds  
 Abstract    The phase diagram of the ternary system Sr/Mo/O has been determined at a temperature of 1000°C. Powder samples of the ternary compounds SrM o04, Sr3M o06, SrM o03, Sr2M o04 and SrMo50 8 were prepared by solid state reactions. The thermochemical data of all ternary compounds were determined.oA new compound, Sr3Mo20 7, with a layered perovskite structure (a = 3.967(1), c = 20.588(5) A, I4/mmm) was found. Rietveld analysis based on powder X-ray diffraction data confirms that the compound Sr2M o04 has the K7NiF4 structure (I4/mmm) with a = 3.9176(1), c = 12.8545(4) A.
