    Notes: Summary The microcristalline phase (NH3OH)2TiF6 has been isolated from aqueous solution. It crystallizes in the tetragonal system with cell parameters:a=9.654±0.005 Å,c=11.546±0.010 Å. The hydroxylammonium fluorotitanate was characterized by vibrational spectroscopy and its thermal decomposition studied by DSC and TG analysis.

    Notes: Summary.  Crystals of (NH3OH)2TiF6ċ2H2O have been isolated. The compound crystallizes in the monoclinic system (P21/c, No. 15) with cell parameters of a=6.203(1) Å, b=10.057(1) Å, c=7.464(1) Å, and β=110.653(6)°. Reactions in the system In (OH)3– NH3OHF – HF have been investigated. Crystals of (NH3OH)3InF6 were isolated from aqueous solution. The compound crystallizes in the trigonal system (R3c) with a=b=c=7.764(2) Å, α=β=γ=97.21(4)°. The thermal decomposition of both compounds was studied by TG and DSC analysis; the decomposition products were characterized by X-ray powder diffraction.

    Notes: Summary Two microcristalline phases have been isolated from aqueous solutions: (NH3OH)2AlF5(A) and (NH3OH)AlF4·H2O(B). They crystallize in the orthorhombic system with cell parameters for A:a=6.475 (3) Å,b=7.295 (3) Å,c=10.827 (5) Å, and for B:a=7.003 (3) Å,b=8.489 (4) Å,c=10.745 (5) Å. The Hydroxylammonium-aluminates were characterized by vibrational spectroscopy and their thermal decomposition studied by DSC and TG analysis.

    Notes: Zusammenfassung Die Systeme Ca(OH)2−Ca(NO3)2, CaO−Ca(NO3)2, SiO2−Ca(OH)2−Ca(NO3)2 und SiO2−CaO−Ca(NO3)2 in verschiedenen Verhältnissen wurden mit Hilfe differentialthermischer, thermogravimetrischer, chemischer und zum Teil röntgenographischer Analysen, sowie durch Messungen der Konsistenzveränderungen in Abhängigkeit von der Temperatur untersucht. Aus den beschriebenen Versuchen ist ersichtlich, daß es bei den angeführten Systemen größtenteils schon bei ca. 380°C zumindest zum teilweisen Schmelzen kommt. Vor allem die Schmelze wie auch der naszente Zustand des CaO und die Ofenatmosphäre beeinflussen die Ausbeute an gebundenem SiO2.

    Description / Table of Contents: Lithium is solved by solid copper with formation of yellow mixed crystals the composition range of which reaching almost up to LiCu4. The volume increment of lithium within this substitution crystals is about 8 cm3, whereas the atomic volume in lithium metal is 13.0 cm3. This change of volume is in agreement with those observed in intermetallic phases containing electropositive and noble metals.
    Notes: Lithium bildet mit Kupfer gelbe Mischkristalle vom Substitutionstyp, die bis nahe zur Zusammensetzung LiCu4 reichen. Das Volumeninkrement des Li in diesen Mischkristallen ist nur wenig größer als 8 cm3 und damit erheblich kleiner als das Atomvolumen des Lithium-Metalls (13,0 cm3); dieses raumchemische Verhalten entspricht dem der intermetallischen Phasen aus unedlen und edlen Metallen.
