27/2/2017· The solubility of calcium in liquid iron at 1823 K and 1873 K (1550 °C and 1600 °C) as a function of calcium potential was studied experimentally. The measurements were performed using a closed molybdenum holder in which liquid calcium and liquid iron were held at different temperatures. The results indie a linear relationship between the activity of calcium, …

1/8/2014· NaAlCl 4 was synthesized by mixing NaCl (Alfa Aesar, 99.95%) and AlCl 3 (Alfa Aesar, 99.99%) with a molar ratio of 1.15:1, followed by heat treatment at 320 C in an argon-filled glove box.
Besides, the capacity of CVO in the pH 10 electrolyte was found to be slightly higher, where the proton or hydronium ion concentration is negligible. Figure 4(b) compares the discharge capacity in both electrolytes at various current densities, showing better capacity retention in the pH 10 electrolyte than in pH 2.3 (59% and 38%, respectively) from 50 mA g-1 to 2000 mA g-1.

1/6/2006· An investigation is made of the microstructural kinetics of a reaction sequence that occurs during electrochemical reduction of hodically polarised samples of porous TiO 2 in molten CaCl 2.Initial reactions, when the TiO 2 both reduces to Ti 2 O 3 via higher-order sub-oxides and reacts with the electrolyte to form iO 3 around the surfaces of the reduced oxide particles, have no obvious
High-purity anhydrous salts of LiCl (99.995%, Alfa Aesar) and CaCl 2 (99.99%, Alfa Aesar) were used. The salts were weighed out in appropriate quantities in ∼500 g batches, mixed, and transferred to an alumina crucible which was then placed in a stainless steel vacuum chaer, the chaer sealed, and loaded into a furnace.
