High-Temperature Electric Conductivity of Magnetite Ore (Magnetite) in Connection with Genetic Properties of the Deposit

摘要

By its degree of perfection, the crystalline structure of natural minerals differs from that of ideal crystals by the occurrence of many distortions and defects. These features of real crystals are variable for the same mineral species from different deposits and belong to typo-morphic mineral properties [1, 2]. Moreover, "different generations of the same mineral, which are formed at successive formation phases and stages of the same deposit, always differ from each other in the compositions, shapes, and sizes of aggregates, structural parameters, and physical properties" [2, p. 17]. In the crystalline structure of real minerals that contain several cation species, their distribution through different positions in the lattice differs depending on the mineral formation conditions and the subsequent thermal history.
