To explain the tensile behavior of the crystalline dielectric and metal films, today mostly the grain boundary model is applied [1]. @Mithoron According to the most widely prescribed Chemistry textbooks (published by the NCERT) in India, thermal stability is measured by the melting/boiling point of an element/compound relative to other members in a group/period/family of compounds (and whether something decomposes on heating or doesn't exist stably at room temperature). Ionic compounds consist of crystalline lattices rather than discrete ion pairs. Also, fluorine being highly electronegative instead of having its electrons wandering around the Al ion would keep much of them to itself while Al achieves a stable electronic configuration.
