Optimal results with perfect price/performance ratio

Mixed metal oxide anodes (MMO) are dimensionally stable and suitable for a wide range of applications. The electrolytes can be alkaline-cyanide to strongly acidic. MMO anodes persuade with a perfect price/performance ratio. They have a low oxygen overvoltage compared to other electrocatalytical surfaces. This results in less energy and minimized organic additive consumption. Customers benefit from significantly prolonged lifespans of the electrolyte. A wide range of anode shapes is possible. Therefore, they can be optimally adapted to the design of the components, which shall be plated. Due to their electrochemical characteristics the anodes are well suited in electroplating for metal deposition out of sensitive electrolytes and for water treatment.

Customized electrode production with pure platinum

PLATINODE describes the refractory metals, such as titanium and niobium, coated with purest platinum. The electrocatalytic functional layers of platinum or various precious metal oxides are used throughout virtually the entire electrochemical industry. The platinum coating is applied by means of high-temperature electrolysis (HTE). The platinum is deposited from a cyanide molten salt bath at temperatures of 500 to 600 °C. The functional platinum layer thus produced, shows excellent adhesion in addition to high ductility and maximum purity. It is possible to produce layers with high platinum thickness, maximum corrosion resistance and excellent service life. Refractory metals such as titanium, niobium, tantalum, molybdenum and tungsten are usually used as the substrate in the production of PLATINODE. However, various special steelalloys and iron/nickel alloys are also used. Expanded metals, sheet metals, round stock, tubes, rods, ribbons and wires of the most varied materials and dimensions are available. The base metals meet the specifications of DIN and ASTM.
