Synthesis Methods. Zirconium and hafnium carbides and nitrides can be synthesized by direct reaction of metal or metal hydride powders with graphite or N reactions are strongly exothermic and can be used in a self-propagated high temperature synthesis (SHS) process [].The reaction of oxides with graphite (carbothermal process) is widely used for industrial synthesis of bulk Aluminum cathodes have long been used for the electrowinning of zinc from zinc sulfatesulfuric acid electrolyte.

Severe corrosion above the electrolyte/air interface limits the life of aluminum cathodes to ca. months for a 6 mm thick plate. The failure characteristics of aluminum cathodes were analyzed using optical microscopy, scanning electron microscopy, energy dispersive x-ray   TDMET Electrowinning Cell TDMET has operated pilot-plant electrowinning cells since Later models produced to lbs of titanium metal in one cathode deposit.
