Lithiumfluorid kristallisiert in der Natriumchlorid-Struktur (KZ = 6) in der Raumgruppe Fm3m (Raumgruppen-Nr. 225) mit dem Gitterparameter a = 402,6 pm. Die Löslichkeit in Wasser beträgt nur 1,3 g/l. Lithiumfluorid ist in Wasser nur wenig löslich, da die Gitterenergie größer als die Hydratationsenergie ist. Wässrige Lösungen reagieren leicht alkalisch (pH 8). Weiterhin bildet es keine Hydrate, wie sie von den anderen Lithiumhalogeniden bekannt sind. WebThe repeatability and reproducibility of the in situ LIF analysis were investigated. For the calibration of the LIF data, two LR oils (a fuel oil and a crude oil) were employed. The degree of soil contamination with petroleum products ranged from the limit of detection (LOD) for LIF analysis (ca. 100 ppm), or below, to more than 10,000 ppm.
