“…Oxides that contain only tetrahedral coordinated B have features dominated by an initial sharp rise in intensity with a maximum at 199 eV (peak b). (25) The fine structure of the boron K-edge in Figure 6 suggests that the majority of the B ions in the specimen have trigonal coordination, and the minority have tetrahedral coordination.…”

“…[145] Als eine der wertvollsten Methoden zur Charakterisierung und Analyse von borhaltigen Substanzen hat sich die EELS erwiesen. Während diese Methode schon in der Vergangenheit zur Untersuchung von Boraten und, in Ausnahmefällen, auch zur Analyse von elementarem Bor, Borcarbid und Boroxiden eingesetzt wurde, [146,147] haben in jüngerer Zeit die Arbeiten von Hofmann et al das große, ausbaufähige Potential nicht nur zur Identifizierung und Reinheitskontrolle von Bor und Boriden deutlich gemacht, sondern über die Analyse der Feinkantenstruktur (ELNES = energy loss near edge structure) und die theoretische Berechnung [148,149] von Spektren auf DFT-Niveau auch Wege zur Strukturbestimmung aufgezeigt. [150][151][152] Abbildung 6 verdeutlicht, wie signifikant die experimentell ermittelte ELNES von B K -Ionisationskanten in hochaufgelösten EEL-Spektren von Bor und Boriden variiert.…”

“…The splitting of (Sb, As) and Al1 sites observed in dumortierite has not been found in holtite . In crystallographic studies of dumortierite, magnesiodumortierite and holtite, B has been reported to occupy only the trigonal site, which is confirmed by study of B K-edge spectra (Garvie et al, 1995;Fleet and Muthupari, 2000). No evidence for deviation from stoichiometry been reported for B in the crystal structure refinements, which is consistent with B contents reported in synthetic dumortierite by Werding and Schreyer (1990;cf.…”
