For instance, the use of titanium metal anodes and titanium wet chlorine gas coolers in the chlor-alkali industry has yielded significant economic benefits and is hailed as a major revolution in the sector.

2. Petroleum Industry In organic compounds, titanium exhibits exceptional stability in all organic acids except five types at elevated temperatures (formic acid, acetic acid, oxalic acid, trichloroacetic acid, and trifluoroacetic acid). Consequently, titanium serves as an outstanding structural material in petroleum refining and petrochemical processes, suitable for manufacturing various heat exchangers, reactors, high-pressure vessels, and distillation columns.

3. Metallurgical Industry Titanium, an active metal with excellent gas absorption properties, serves as an outstanding degassing agent in steelmaking. It reacts with oxygen and nitrogen that precipitate during steel cooling. Adding a small amount of titanium (0.1%) to steel enhances its toughness and elasticity. Titanium also serves as a crucial alloying additive in steel and aluminum production. Possessing superconductivity, it is a common superconducting material. Furthermore, titanium exhibits exceptional stability in acidic solutions containing metal ions, making it widely applicable in hydrometallurgical processes—such as the electrolytic production of non-ferrous metals like copper, nickel, cobalt, and manganese.

4. Fertilizer Industry Urea is a vital fertilizer. During its production, urea, ammonia, ammonium carbamate, and their mixtures exhibit strong corrosivity under high-temperature and high-pressure conditions. Replacing stainless steel with titanium significantly extends equipment lifespan and reduces maintenance time. Consequently, titanium materials are now used in most primary equipment for urea production.

5. Seawater Desalination and Shipbuilding Industry Titanium exhibits superior resistance to seawater corrosion compared to all other metals, maintaining exceptional stability whether exposed to stationary or high-velocity seawater flows. Consequently, titanium is an ideal material for seawater desalination units. Its application in this field will continue to expand. Titanium's strong resistance to seawater and marine air corrosion, combined with its high strength and low weight, makes it an ideal structural material for shipbuilding. It is already widely used in numerous components of various naval vessels and deep-water submarines.

6. Power Industry Titanium exhibits good stability in hot water containing corrosive substances like chlorides and sulfides. Consequently, it is extensively used in thermal power plants as cooling tubes for heat exchangers. Replacing copper-nickel alloy tubes with thin-walled titanium tubes not only significantly extends service life but also drastically reduces maintenance time, yielding remarkable economic benefits.

7. Paper and Textile Industries Titanium exhibits exceptional corrosion resistance against bleaching agents like chlorine dioxide, chlorite, and chlorite salts. Consequently, it plays a vital role in bleaching equipment within textile dyeing and paper manufacturing industries. For instance, titanium-fabricated chlorite bleaching machines demonstrate excellent performance. Additionally, it serves as spinnerets in synthetic fiber production and other related industries.

8. Other Applications Titanium resists corrosion by the human body and is non-toxic to humans. Consequently, it finds extensive use in the medical and pharmaceutical industries. Titanium's excellent gas absorption properties also enable its widespread application in electronic vacuum technology and high-vacuum technology.
