Application Of Titanium In Chemical, Metallurgical And Other Industries

Another notable feature of titanium is its good corrosion resistance. This is because it is easy to form a dense oxide film on its surface to protect the titanium matrix from corrosion by the medium. Pure titanium has excellent corrosion resistance. It is often used in the chemical, petroleum, textile, metallurgical and other industries to make anti-corrosion equipment or parts.

The scope of application of titanium in the chemical and metallurgical fields includes the manufacture of various equipment, electrolysis plates, reactors, heat exchangers, separators, absorption towers, coolers, concentrators, and various continuous supporting tubes, Valves, fittings, gaskets, pumps, etc.

In the production of chlor-alkali, titanium anodes (coated with ruthenium) are used to replace the original graphite anodes, forming a "dimensionally stable electrode" with no adjustment of the electrode spacing, and the service life is more than 10 times longer than that of graphite anodes. This kind of titanium anode is semi-permanent, the current density is nearly double that of graphite anode, the production capacity is also nearly doubled, and the electricity is saved by 15%. Moreover, it can improve the quality of alkali, and has received excellent economic benefits. It is known as a revolution in chlor-alkali industry. The annual production of 10,000 tons of caustic soda requires 5 tons of titanium.
