The present review article covers the synthesis of inorganic fluorides using two types of molten media – molten salt fluxes and ionic liquids (IL). Molten salt syntheses (MSS) are applicable across widely-varying temperatures, ranging from 150 to 800 °C. Lowering the synthetic temperature results in smaller particle sizes, from a few millimeters at 800 °C to about 30 nm at 150 °C, whereas increasing the reaction temperatures accelerates hydrolysis of fluorides. IL syntheses allow the isolation of non-agglomerated nanoparticles without use of the sophisticated equipment. MSS syntheses at 300 °C or higher allowed the synthesis of equilibrium phases.

熔盐熔剂和离子液体介质中无机氟化物的合成

本综述文章涵盖了使用两种类型的熔融介质（熔融盐熔剂和离子液体（IL））合成无机氟化物的方法。熔融盐合成（MSS）适用于150至800°C的各种温度范围。降低合成温度会导致较小的粒径，从800°C的几毫米到150°C的约30 nm，而提高反应温度会加速氟化物的水解。IL合成无需使用复杂的设备即可分离未团聚的纳米颗粒。在300°C或更高的温度下合成MSS可以合成平衡相。
