Further to previously reported studies of corrosion of noble metals and refractories in molten alkali carbonates,1  similar studies were made on gold-20 percent palladium, nickel and Type 347 stainless steel at 600-700 C (1112-1292 F).

Type 347 stainless steel was found highly resistant to attack, possibly due to passivation by a film of LiFeO2. Nickel was embrittled at 600-700 C with the intergranular formation of NiO. The small but finite attack of the gold-20 percent palladium was accompanied by formation of sodium palladiate.
