Röntgenographische Untersuchung des Systems KFMgF2

Abstract: Das früher auf Grund thermischer Analyse aufgestellte Zustandsdiagramm des Systems KFMgF2 wird auf röntgenometrischem Wege bestätigt. Außer der ein ausgeprägtes Schmelzpunktsmaximum aufweisenden Verbindung KMgF3 mit Perowskitstruktur tritt darin eine inkongruent schmelzende Verbindung K2MgF4 auf, die tetragonal kristallisiert. Sie unterscheidet sich von den aus Schmelzen mit 50 bis 78,5 Mol‐% KF primär sich abscheidenden Mischkristallen dadurch, daß sie aus regelmäßig miteinander abwechselnden KF‐ und KMgF3‐S… Show more

“…Experimental studies have been performed to determine the ground state properties [4][5][6][7][8] and elastic constants at ambient pressure [9,10] and their dependence with pressure and temperature [11]. The high-pressure structural behavior of KMgF 3 was recently investigated by the high-pressure powder Xray diffraction [12].…”

“…In addition the physical properties of KMgF 3 may have implications for understanding of the Earth's lower mantle 7,8 . KMgF 3 was first synthesized by van Arkel 9 and has a simple cubic perovskite structure at room temperature 10 . KMgF 3 demonstrates great stability under high compression and has not been found to undergo any phase transition at any temperature or pressure, suggesting it may be used as an internal X-ray calibrant 11 .…”
