SMOOTH ELECTRODEPOSITS OF MOLYBDENUM FROM KF-K//2B//4O//7-K//2MoO//4 FUSED SALT MELTS.

An adherent and visually smooth deposit of molybdenum has been electrolytically deposited on copper, nickel, molybdenum, stainless steel, mild steel and graphite substrates in a KF-K//2B//4O//7-K//2MoO//4 fused salt melt at temperatures in the range 998-1173 K and current densities in the range 110-660 A m** minus **2. The deposits were not as hard as those obtained from KF-B//2O//3-MoO//3, KF-B//2O//3-Na//2MoO//4, KF-B//2O//3-K//2MoO//4 and KF-Na//2B//4O//7-Na//2MoO//4 fused salt melts, a little harder than the smooth deposits obtained from a KF-Li//2B//4O//7-Li//2MoO//4 fused salt melt, and in spite of the use of a graphite cell, comparable with that of a molybdenum button which was prepared by plasma-arc-melting a commercially available molybdenum sheet.
