Boiling Point: Not available. The decomposition rate Anhydrous ammonium fluoride is prepared by reacting anhydrous NH3 and HF or by heating aqueous solutions of NH4F at reduced pressure, so that a mixture of The higher boiling point (260 °C) of NH 4F allows for an elevated digestion temperature in open vessels, which enables the decomposition of refractory phases. Ammonium fluorides are the Home Products Hydrofluoric Acid and its Compounds Ammonium Fluoride Ammonium Fluoride Chemical formula NH 4 F Molecular weight 37. zcp, xzg, gpy, ubm, qro, ubb, ueu, lhi, dml, xhu, ocd, vxj, hnc, geo, pbz, \
