The study of the properties blast-furnace slags requires an integrated approach, including various research methods. purpose work is to substantiate resource value Zaporizhstal dump blast furnace slag. methods were used: X-ray phase, petrographic, gamma-spectrometric analysis and electron probe microanalysis. slag dispersed into fractions, since minerals have different hardness. Fractions (mm) ...

The liquidus surfaces and the isothermal section at 1073K of the pseudo-ternary CaO-Fe2O3-B2O3 system were determined in a composition range of less than 50mol% B2O3 using the thermal analysis and X-ray diffraction. The liquidus surface which is in equilibrium with Fe3O4 spreads over a wide composition range and that in equilibrium with Fe2O3 extends long and narrow toward CaO B2O3 and then tow...

Separating P2O5 from steelmaking slag is the key to achieving optimum resource utilization of slag. If P-concentrating 2CaO?SiO2–3CaO?P2O5 solid solution was effectively separated, it can be a potential phosphate and remaining rich in Fe2O3 CaO reutilized as flux process. In this study, low-cost method selective leaching adopted, hydrochloric acid selected agent. The dissolution behavior quench...

Gamma dicalcium silicate (γ-2CaO∙SiO2, abbreviated as γ-C2S) is considered a potential candidate construction material owing to its high carbonation reactivity and consequent CO2 absorption. This study investigates the diffusion of CO2, physical process, into hardened cement paste resulting carbonation, chemical process. diffuses from region concentration one lower concentration, which inner co...

Colemanite (2CaO.3B2O3.5H2O) is a type of boron mineral that found in various regions our country excess compared to the world and at same time has high commercial value. In this study, effects solid / liquid ratio, acid concentration, particle size, mixing speed reaction temperature parameters dissolution kinetics colemanite sodium bisulfate solution were investigated. According experimental r...

The most basic assumption of the classical nucleation theory (CNT) is to treat nucleus/liquid surface energy, r, as a macroscopic property having a value equal to that of a planar interface, r1. Therefore, when the CNT is used to analyze experimental data, the size dependence of surface energy is often neglected. To date, there has been no reliable method to measure the surface energy of the nu...
