Some natural single crystals are under the their name, such as magnetite, Fe3O4 and/or included under their chemical name, mineral as the sulfide, ZnS and sphalerite, ZnS, where such two compounds have been involved zinc in comparative studies. state Technical — Primarily as (iii) application material. The development of research in areas such as geomicrobiology and environmental mineralogy and geochemistry, is also leading to a greater appreciation of the role of sulfides (particularly the iron sulfides) in the geochemical cycling of the elements at or near the surface of the Earth.

Self-diffusion of iron in single crystals of ferrous sulfide and magnetically saturated iron by Richard Redfield Hobbins Download PDF EPUB FB2

By use of radiotracer techniques, the iron self-diffusion coefficient in ferrous sulfide single crystals above K was found to be D = D 0δ exp {−[(81±4) + (84±20)δ]/RT}where the exponential units are kJ/mole, D 0 is ± ×10−2 and ± × 10−2 cm2 sec−1 for diffusion in the a- and c-directions, respectively, and δ is the deviation from stoichiometry as given in the Cited by: The reason for this is that from the viewpoint of classical diffusion studies ferromagnetic iron is a "low-temperature phase" since at the Curie- temperature (Tc = I0h3 K) the self-diffusion coefficient is already as low as cm2s Self-diffusion in b.c.c.~-iron, which is stable below T~,~ = K was studied repeatedly in the past (I-7).Cited by:   The kinetics and mechanism of iron sulfidation have been studied as a function of temperature (– K) and sulfur pressure (10− atm).

It has been stated that a compact Fe1−yS scale on iron grows according to the parabolic rate law as a result of outward lattice diffusion of metal ions through cation vacancies.

On the other hand, the remarkable strength of the nanocrystalline iron-carbon alloy is reasonably commensurate with the Hall-Petch strengthening to be expected from grain refinement alone; in fact, this magnitude of strengthening is also found with pure nanocrystalline iron.
