have been used to determine activity coeffcients of Na,O in molten NaCl, Na,SO,, and Na,CO,. Extreme negative deviations from Raoult's law were observed (y -z 10e3). In NaCl and Na,SO,, y is independent of concentration below 1 m/o Na,O, but in Na,CO,, the activity is nearly independent of concentra

β¦ Synopsis
The long term stablhtles of several reference electrodes m contact with an acldlc Na,SO, melt at 1200 K were studled These Included the spec~tic Na+ Ion probes Ag/Ag+ mulhte or /3-Al,O, or fused-slhca, and O,(Pt)/Na,O-WOJfused-slllca, and the specific 02-Ion probes CaO-and Y,O,-stabdlzed zlrcoma Corrosion attack of the electrolyte tubes led to drifts m the measured potentials The Ag/Ag+ fused-slhca and the Y,O,-stablhzed zlrcoma electrodes were found to provide the best stablhtles

The hot corrosion resistance of sprayed and atomized Fe40AlΓΎ0.1B and Fe40AlΓΎ0.1BΓΎ10Al 2 O 3 intermetallic materials have been evaluated in molten Na 2 SO 4 at 900 and 1000 8C using polarization curves and polarization resistance measurements. The results are supported by electron microscopy and micr
Potential of Li, K/Li+, K+ dynamic reference electrode has been measured against HF/H2 gas electrode of several partial pressures in a LiF-KF eutectic melt. Experimental results show that this dynamic reference electrode can be used as a conventional reference electrode, since the thermodynamic sign
