Kraydenko [et al.] // IOP Conference Series: Materials Science and Engineering. — 2016. — Vol. 135 : Issues of Physics and Technology in Science, Industry and Medicine : VIII International Scientific Conference, 1–3 June 2016, Tomsk, Russia : [proceedings]. — [012021, 7 p.].
Abstract: The technique of fluorite-phenacite-bertrandite ores from Russian Ermakovskoe deposit processing by ammonium bifluoride is described. To determine the temperature mode and the thermal dissociation mechanism of ammonium tetrafluoroberyllate (the product of ammonium-fluoride leaching of the ore) the TG/DTA have been carried out. By IR spectroscopy and XRD the semi-products of ammonium tetrafluoroberyllate thermal dissociation have been identified. The hygroscopic low-temperature beryllium fluoride forms higher than 380°C. The less hydroscopic form of BeF[2] have been produced at 600°C.
