Fluoride Model Systems: II, The Binary Systems CaF2-BeF2, MgF2-BeF2, and LiF-MgF2

Data obtained by quenching, thermal, and high‐temperature X‐ray techniques are presented for the three binary systems CaF2–BeF2, MgF2–BeF2, and LiF–MgF2. The systems CaF2–BeF2 and MgF2–BeF2 are presented as weakened models of the systems ZrO2–SiO2 and TiO2–SiO2, respectively. The compound CaBeF4 is...

Description
Summary:Data obtained by quenching, thermal, and high‐temperature X‐ray techniques are presented for the three binary systems CaF2–BeF2, MgF2–BeF2, and LiF–MgF2. The systems CaF2–BeF2 and MgF2–BeF2 are presented as weakened models of the systems ZrO2–SiO2 and TiO2–SiO2, respectively. The compound CaBeF4 is a model of ZrSiO4 (zircon). New data obtained for the system LiF–MgF2 explain many discrepancies among the results of previous authors. Solid solution is almost complete between LiF and MgF2 at elevated temperatures, but a small gap occurs at the eutectic (735°C.) with extensive exsolution at lower temperatures.
