Physicochemical properties of tungsten carbide powders prepared from ionic melts

High Surface Area Mo2C and WC Prepared by Alkalide Reduction

“…A number of methods have been reported capable of the synthesis of high surface area Mo 2 C and WC including gas-phase reactions, 2,3 gas-solid reactions, [4][5][6][7][8][9] or electrochemical 10 and solution state methods. [11][12][13][14] Particularly high surface areas (50-200 m 2 g -1 ) have been achieved by converting solution-derived precursors to the respective carbides, 14 reaction of MoO 3 or WO 2 vapors with activated carbon, 8,9 and sonochemical methods.…”

Advances in high-temperature electrochemical synthesis in ionic melts by the onset of XXI century

“…, and WO 4 2! ions with molten Na 2 WO 4 as supporting electrolyte occurs at close potentials [40,60], which allows their joint reduction, i.e., the high-temperature electrochemical synthesis of the carbides.…”

“…Electrolytic deposition of Mo 2 C coatings was performed from the Na 2 WO 4 3 Li 2 MoO 4 3Li 2 CO 3 oxide melt [40,60]. This system allows joint electrolytic reduction of the MoO 4 2!…”

Syntheses of metal nitrides, metal carbides and rare-earth metal dioxymonocarbodiimides from metal oxides and dicyandiamide

“…An effective and general route to synthesize nitrides and carbides, rapid solid-state methathesis (SSM) has been developed in the past decade [10][11][12][13]. Other routes including solvothermal, carbothermal, sonochemical and electrochemical methods, gasphase reactions, metal-organic polymeric precursors routes are successful in synthesizing some nitrides and carbides [14][15][16][17][18][19][20][21][22].…”
