Titanium in the Process of Smelting Pig Iron with an Increased Silicon Content
In connection with future utilization of magnetite titanium ores deposited in Poland in the region of Suwałki the test were performed to get information regarding the influence of titan and vanadium admixtures on the quality of pig iron and the run of blast furnace process. As a blast furnace charge, there were used magnetite titanium concentrates similar to the ores deposited in the Suwałki re...
متن کاملMagnetic Anisotropy in Silicon Iron
The first anisotropy constant for Fel-%Si, is determined by torque measurements, for x up to 10 atomic per cent, in the temperature range 21-300 OK. The values, as extrapolated to 0 OK, vary linearly with silicon content. Using the expressions obtained by Keffer and Oguchi it is shown that K1 at 0 OK should vary as { 1 (a + 2) x ) where a is the ratio of dipole contribution to the total value o...
متن کاملIron-silicon alloy in Earth's core?
We have investigated the phase relations in the iron-rich portion of the iron-silicon (Fe-Si) alloys at high pressures and temperatures. Our study indicates that Si alloyed with Fe can stabilize the body-centered cubic (bcc) phase up to at least 84 gigapascals (compared to approximately 10 gigapascals for pure Fe) and 2400 kelvin. Earth's inner core may be composed of hexagonal close-packed (hc...
متن کاملPrecipitation of interstitial iron in multicrystalline silicon
The internal gettering of iron in silicon via iron precipitation at low processing temperatures is known to improve solar cell efficiencies. Studies have found that the optimal temperature lies in the range of 500 o C-600 o C. In this paper, we present experimental results on quantitatively analysing the precipitation of interstitial Fe in multicrystalline silicon wafers during the 500 o C-600 ...
متن کاملIron absorptive function of neonatal pig intestine.
To define the iron absorptive phase across the intestinal mucosa of neonatal pigs, the final SgFe concentration ratio of serosal to mucosal medium of everted gut sac at 1 hr incubation was measured. With .2 btg carrier iron (ferric citrate with molecular weight of 1,500) per milliliter of both the serosal and mucosal medium, the duodenum transported the iron against the concentration gradient f...
