제품 설명

World production of iridium is small, only a few metric tons (tonnes) per year, and it is one of the least abundant and most expensive metals. It is produced as a by-product of nickel smelting and has few applications as a pure metal. In a pure form, it is used for electrodes in high-performance spark plugs and crucibles for the preparation of single crystals of certain electronic and optical glasses. As an alloying element, it increases the corrosion resistance of titanium and palladium, and the strength, hardness, and corrosion resistance of platinum. Despite its corrosion resistance, you are most likely to come across iridium indirectly. It is one of the mixed metals in mixed metal oxide-coated titanium anodes for impressed current cathodic protection. Those involved in nondestructive testing may come across iridium-192 as an isotope in radiography.

Titanium DSA electrodes are the state of art as anode for a wide range of electrochemical applications. The excellent stability of titanium against surface and pitting corrosion make it dimensionally stable permitted dramatic innovations in equipment design, operation conditions and energy consumptions of many electrolysis processes. The application of coating containing mixed metal oxides (MMO) such as RuO2,IrO2,TiO2 and Ta2O5 allows to reduce remarkably the overpotential for anodic chlorine and anodic oxygen evolution. Additionally the MMO coated anode's excellent stability consequently do not contaminate the electrolysis system, improving the products purity and maintenance costs.

Advantages of titanium anodes compared with the traditional process of applying platinum-plated electrodes in alkaline copper as follows:

1. High current efficiency, good corrosion resistance, long anode life, high current density (up to 10000 A/m2). 2. Energy saving: As we all know, platinum-plated electrode is a high oxygen potential (1.563V, compared with mercurous sulfate) electrode, while titanium anode with precious metal oxide coating is a low oxygen precipitation overpotential (1.385V, compared with mercurous sulfate) electrode, which is easier to precipitate oxygen in the anode precipitation zone. As a result, the tank pressure is relatively low during the electrolysis process, thus saving more electrical energy. This phenomenon is evident in the alkaline copper plating solution for copper foil post-treatment. 3. No pollution:Precious metal oxide coated titanium anode coating is a ceramic oxide of precious metal iridium, which is a rather stable oxide, almost insoluble in any acid or alkali, and the oxide coating is only 18~40μm, so the oxide content of the whole coating is very small. Therefore, the precious metal oxide coated titanium anode will not pollute the plating solution and is basically the same as platinum plated electrode.

4. High cost performance:In order to achieve the same service life of platinum-plated electrode (coating thickness 3.5μm), the price of precious metal oxide coated titanium anode is about 80% of that of platinum-plated electrode. Precious metal oxide coated titanium anode has good electrochemical stability in alkaline copper plating electrolyte, and has excellent electrocatalytic activity and durability. 5. In the printed circuit board industry, copper plating requires pulse-periodic reverse current (PPR). We know that in an environment containing chlorides in sulfuric acid systems, platinum-coated titanium anodes will flake off the platinum layer after working for a period of time. However,precious metal oxide coated titanium anodes can effectively change this situation. 6. Low maintenance cost: Compared with traditional soluble electrodes (graphite and lead alloy electrodes), precious metal oxide coated titanium anodes do not require frequent stoppages for cleaning and replenishment of anodes, nor do they require frequent replacement of anode packages and recoating of anodes, which improves productivity and reduces labor costs; 7. Under the same working conditions, the lifetime of titanium anodes with precious metal oxide coating depends on the working current density, temperature and composition of the plating solution.
