Thermal behavior of ammonium-containing titanium and germanium fluoride complexes (NH4)4Li2(AF6)3 and NH4NaAF6 (A = Ge or Ti)

The compounds (NH4)4Li2A3F 18 and NH4NaAF6 (A = Ge or Ti) were studied thermogravimetrically. These fluoro complexes are thermolyzed in the range 230-450°C. Measurements on a differential scanning microcalorimeter revealed reversible phase transitions in NH4NaAF6 at T 1 = 126°C and T 2 = 111°C.

Determination of impurities in germanium tetrafluoride by IR spectroscopy and gas chromatography

Using high-resolution Fourier-transform IR spectroscopy and gas chromatography, we have identified more than 20 impurity species, in concentrations from 10-1 to 10-5 vol %, in GeF4 samples of different isotopic composition
