Molten Salt Electrolysis / Aqueous Solution Electrolysis
Molten Salt Electrolysis
Metals such as aluminium, lithium, and sodium, which have high ionization tendencies and do not precipitate in aqueous electrolysis, are industrially produced using this method.
How It Is Used
In electrolysis applications, graphite is used as electrolytic plates for extracting target products from ores and brine (seawater, salt lake water) through electrolysis, taking advantage of graphite’s excellent heat resistance, electrical conductivity, and corrosion resistance.

Application Examples
Graphite is used as an anode, a cathode, or both as electrolytic plates for molten salt electrolysis.
In molten salt electrolysis, corrosive chlorine gas may be generated depending on the type of salt used. Our extruded specialty graphite, which excels in electrical conductivity, heat resistance, and corrosion resistance, is utilized as electrode plates for electrolysis.
The Advantages of SEC Carbon Products for Molten Salt Electrolysis
Excellent Heat Resistance
Our Graphite can be used up to approximately 3,000℃ in inert atmospheres and up to about 400℃ in oxidizing atmospheres. One of special characteristics of graphite is that mechanical strength increases as the temperature gets higher up until 2,500℃ in inert atmospheres.
Excellent Electrical/Thermal Conductivity
Our Graphite has the similar thermal and electrical conductivity as those for metal.
Excellent Thermal Shoch Resistance
Our Graphite is extremely resistant to the appearance of cracks and fractures even when exposed to sudden heating or cooling.
Excellent Chemical Resistant
Our Graphite shows outstanding corrosion resistance against various chemicals.
