Morana, S J; Simons, G F

The method of production of BeF/sub 2/ from the NH/sub 4/HF/sub 2/ + BeO reaction is modified so that only 1 mole (instead of 2) of NH/sub 4/HF/sub 2/ is required per mole of BeO, the reaction is speeded up, and a BeF/sub 2/ product is obtained which has a lower melting point and is easy to pour at high temperatures. The modified process consists of heating BeO with 100 to 120% of the stoichiometric amount of NH/sub 4/HF/sub 2/ in the presence of an amount of H/sub 2/O one-third of the BeO weight to promote BeF/sub 2/ formation and then heating the reaction product at>600 deg C in the presence of NaCI or MgF/sub 2/. The final BeF/sub 2/ product. prepared in this way in 5 hr, can be easily poured at 800 to 850 deg C and, at room temperature. is a hard friable material of spongelike appearance and of very low density compared with the product from the unmodified process. It contains NaCl or MgF/sub 2/. but that does not matter if the product is to be used to produce beryllium. (D.L.C.)
