Abstract
"The Structure and Properties of Ionic Melts" was the title of a Faraday Society Discussion held in Liverpool in 1961; it dealt exclusively with molten inorganic salts. "Ionic Liquids" was the title of Chapter 6 of the textbook Modern Electrochemistry by Bockris and Reddy, published in 1970: it discussed liquids ranging from alkali silicates and halides to tetraalkylammonium salts.
