, p. 153 - 157 (2008/10/09)
Solid-phase interactions of (NH4)2SiF6 with silicon oxide are investigated; calcium oxide; potassium carbonate; and zirconium, aluminum, and barium fluorides. The phase composition is investigated, and the chemical composition is determined for the interaction products, including sublimates. The IR spectra and DTA curves are measured. It has been shown that ammonium hexafluorosilicate is an active fluorinating agent at temperatures above the thermal stability temperature of ammonium hydrodifluoride, which may be of interest for chemical technology.
