Materials for metal anode and cathode plates in chloride electrolyte systems
Thread Content
Metal electrolysis, such as that of zinc, is usually carried out in a sulfate system. Generally, lead-silver alloy plates or multi-element alloy plates are used as the anode, while aluminum plates are used as the cathode. Question: What material should be used for the anode and cathode plates in electrolyzing metals in a chloride salt system?
In chloride-based systems, the anode can be either graphite or ruthenium-coated titanium. Graphite anodes have a shorter lifespan and tend to contaminate the cathode products, while titanium anodes have a longer lifespan and are relatively lightweight, but they are more expensive. The cathode can be made of aluminum or titanium
Ruthenium-titanium anodes are currently widely used, offering high current, stable voltage, and a long service life!
-- Ruthenium titanium? It seems that the price of this alloy isn’t cheap, right? --
4# FILTRATION-MAN is simply a layer of ruthenium or ruthenium compounds coated on a titanium substrate; the thickness of this layer follows certain standards, and the price is calculated per square meter. Slightly cheaper than the iridium compounds used as anodes in sulfuric acid electrolytes
-- Iridium! Even worse, it seems to be the most expensive metal. --
6# FILTRATION-MAN: Last time I bought three iridium-plated titanium anodes, 700mm*950mm in size, with each one costing 4500 yuan. They are expensive, but they work very well
-- Haha, 4500 is much cheaper than I thought. --
