Data obtained by quenching, thermal, and high‐temperature X‐ray techniques are presented for the three binary systems CaF 2 –BeF 2 , MgF 2 –BeF 2 , and LiF–MgF 2 . The systems CaF 2 –BeF 2 and MgF 2 –BeF 2 are presented as weakened models of the systems ZrO 2 –SiO 2 and TiO 2 –SiO 2 , respectively. The compound CaBeF 4 is a model of ZrSiO 4 (zircon). New data obtained for the system LiF–MgF 2 explain many discrepancies among the results of previous authors. Solid solution is almost complete between LiF and MgF 2 at elevated temperatures, but a small gap occurs at the eutectic (735°C.) with extensive exsolution at lower temperatures.
