Modeling of Physical Chemical Properties of Oxidic Combinations in Metallurgical Melts

摘要

For more than 25 years they are using model parametes of the system of unpolarized ion radii (SUIR) to study PHYSICAL & CHEMICAL PROPERTIES OF OXIDIC COMBINATIONS. The essence of the approach based on SUIR utilization consists in the refusal from traditionally shaped approach in steel making which iss based on the notions of electric neutrality of a combination, ion charges being multiple to integral numbers & exact spherical shape of electronic clouds. The fairness of such a solution is explained by both theoretical & applied researches of (1-7). Charges of elements differ a lot from their valency & taking this factor into account may become quiter useful while studying macro propetties of a complex combination 32 SiO_2+16,3 Al_2O_3+32 CaO+4,4 MgO+6,7 CaS for CaO we have Z_ca=0,927; Z_0=-2,469(3).
