Abstract
Molten oxide electrolysis (MOE) is the electrolytic decomposition of a metal oxide, most preferably into liquid metal and oxygen gas. The successful deployment of MOE hinges upon the existence of an inert anode capable of sustained oxygen evolution z taveniny při cca 1600°C.

Herein we report the results of a program of materials design, selection, and testing of candidate anode materials and demonstrate the utility of iridium in this application. An electrolysis cell fitted with an iridium anode operating at 0.55 A cm−2 produced liquid metal and oxygen gas by the decomposition of iron oxide 5 or 10 wt % FeO dissolved in a MgO(16 wt %)–CaO(18 wt %)–Al2O3(20 wt %)–SiO2 (46 wt %).

An iridium wire, 0.5 mm diameter, 9.5 cm long, immersed 1.4 cm into the melt, served as the anode, while a molybdenum rod, 3.17 mm diameter, served as the cathode. The cell was also fitted with a reference electrode consisting of a molybdenum rod, 3.17 mm diameter. Temperature was set at 1575°C.

Galvanostatic electrolysis was performed at a current density of 0.55 A cm−2 for a period of 6.35 h on a melt composed of the alumino-silicate supporting electrolyte containing 5 wt % FeO / the electrolyte.

The mass of the iridium wire was 440.13 and 437.12 mg before and after electrolysis, respectively. The 3.01 mg weight loss of the entire iridium wire is equivalent to a consumption rate of ∼7.7 mm/year when ascribed only to the section of wire immersed.

The erosion rate of iridium was measured to be less than 8 mm y−1. The stability of iridium is attributed to a mix of mechanisms including the electrochemical formation and simultaneous thermal decomposition of a surface film of iridium oxide.

The condition of the iridium anode is depicted before and after electrolysis (the entrained electrolyte was removed by immersing the iridium wire in 47–51% HF aqueous solution for 45 min) in Figs. 4a and 4b, respectively, showing a change in surface finish but no perceptible change in dia meter ani o metr.



The black trace of Fig. 3 shows that the potential on the anode as measured between it and the reference electrode remained nearly constant.



The performance of this material as an inert anode for MOE was assessed in the context of iron production by electrolysis of FeO dissolved in an alumino-silicate supporting electrolyte.

Fake! Nothing was assessed!!

Kto Vám dá (zapůjčí) za 8 q schrotu alespoň 3,01 kg Ir, když Ir planetka stále nepřichází do Amerického Zálivu nebo alespoň do NYC či DC?
