A nonaqueous solvent system particularly useful in coordination chemistry. Fused salts are a large class of liquids which are composed largely of ions. Many simple inorganic salts melt at rather high temperatures (greater than 600°C or 1000°F), forming liquids which have high specific conductivities, 1–6 ohm⁻¹. cm⁻¹ (Table 1). There are, however, a number of exceptions to this generalization; for example, the electrical conductivity of AlCl₃ decreases sharply upon melting due to the formation of molecular liquid (Al₂Cl₆).
