Uses of titanium in Anodes
What is a titanium anode?
An anode is a positively charged electrode through which electrons will leave a given electrical device. When the term ‘titanium’ is applied to it, it simply means an anode that is made from titanium.
Other materials that may be used include aluminum, zinc, copper and brass depending on application. There are basically three common types-sacrificial, plating and mixed metal oxide. With sacrificial anodes, applications are in the marine industry, pipelines and vessels. Plating anodes are used in electroplating applications while mixed metal oxide (MMO) anodes are used in applications that require an electrolysis reaction.
Titanium anode falls in the MMO category. They are commonly used in environments such as seawater, freshwater, soil and mud.
Why is titanium used?
Thanks to their high strength to weight ratio, titanium anodes are more valued compared to others such as copper, aluminum, zinc or brass.
In terms of Titanium anode, titanium is the material of choice because it doesn’t cast a bundle and has a relatively high lifespan. In addition, titanium is light in weight.
Last but not least, titanium is highly corrosive resistant which makes it ideal in applications where corrosion is of great concern.
What type of titanium is used?
Depending on specific use of the titanium anode, different types of titanium may be used. It is possible to use grade 1, grade 2, grade 3, grade 11, grade 12 or grade 5 titanium. Each grade carries its own characteristics that make it idea for use in a particular application.
Grade 1 titanium for example is the softest and purest thus making it easy to manipulate into various applications. It may be used in chemical processing and the marine industry. In addition, it may be used in Chlorate manufacturing, the medical industry, architecture and in the making of automotive parts.
