The prominent feature of titanium is its strong corrosion resistance, which is due to its strong affinity to oxygen, which can generate a dense oxide film on its surface, which can protect titanium from medium corrosion. Titanium metal can form passive oxide film on the surface in most aqueous solutions. Therefore, titanium has good stability in acidic, alkaline, neutral saline solution and oxidizing medium. It has better corrosion resistance than existing stainless steel and other non-ferrous metals, and even can be compared with platinum.
- Chemical Industry
Titanium is an excellent corrosion-resistant material in chemical industry, and it has been widely used as it gets older. For example, the use of titanium metal anode and titanium wet chlorine cooler in chlor-alkali industry has achieved good economic results and is known as the revolution in chlor-alkali industry.
- Petroleum Industry
Titanium has excellent stability in organic compounds except five organic acids (formic acid, acetic acid, oxalic acid, trichloroacetic acid and triacetic acid) at higher temperatures. Therefore, titanium is an excellent structural material in petroleum refining and petrochemical industry. It can be used to make various heat exchangers, reactors, high pressure vessels and distillation towers.
- Metallurgical Industry
Titanium is a kind of active metal, which has good gas absorption property. It is an excellent paint remover in steelmaking industry. It can combine oxygen and nitrogen precipitated from steel during cooling. A small amount of titanium can make the steel tough and elastic. Titanium industry is an important alloy additive in steelmaking and aluminium industry. Titanium is widely used in hydrometallurgical gold industry, such as electrolysis of copper, nickel and cobalt, and Namanganese.
- Fertilizer Industry
Urea is an important chemical fertilizer. It is corrosive under high temperature and high pressure in the production process. The service life of the equipment is greatly increased and the maintenance time is greatly reduced when titanium is used instead of non-embroidered steel. So Titanium is used in the main equipment of urea production at present.
- Seawater desalination and shipbuilding industry
Titanium is an ideal structural material for shipbuilding industry because of its strong corrosion resistance to sea water and sea air, high strength and light weight. It has been widely used in many parts of warships.
- Electric Power Industry
Titanium has good stability in many corrosive hot water containing chloride, sulfide and so on. Therefore, titanium has been widely used as the cooling pipe of heat exchanger in thermal power plants, which greatly reduces the overhaul time and has a remarkable economic effect.
- Paper and Textile Industry
Titanium has special corrosion resistance to chlorine dioxide, chlorite, chlorite and other bleaching agents. Therefore, titanium has an important application in bleaching equipment of textile printing and dyeing industry and paper industry.
- Medical and other aspects
Titanium has good affinity and is harmless to human body. Therefore, it can be widely used in medical and pharmaceutical industries. Titanium has good gas absorption performance and is widely used in electronic vacuum technology and high vacuum technology.
