Single fused salt electrolysis

The fused salt electrolysis technique was successfully applied to the preparation, also as single crystals, of several transition metal compounds. A review on this subject was published by Wold and Bellavance (1972). A systematic treatment of several reactions and processes, was presented possibly somewhat obsolete now and with a drawback due to the presence of several impurities in the synthesis products. The preparation of the following compounds was especially discussed. 

In recent years, more novel methods have been developed by chemists in order to hasten the reaction between solids or to grow single crystals of new and exotic solids. Among those included in the following syntheses are electrolysis of fused salts, chemical transport, and hydrothermal crystal growth. 

Both carbides are prepared as crystals from fused-sait electrolysis of carbonate-borate-fluoride-metal oxide salt baths. Large crystals of MojC are grown in a process d where the powdered carbide is added to a molten region on a growing solid rod. Zone refining also gives single crystals.
