Titanium

Category: Science and Technology | Mineral Resources | Industrial Economy

UPSC Notes

Titanium is a transition metal valued for its high strength-to-weight ratio, corrosion resistance and ability to perform under demanding conditions. It is widely used in aerospace, defence, medical implants, chemical processing and specialised industrial equipment.

Titanium is generally obtained from minerals such as ilmenite and rutile. Titanium dioxide is also widely used as a white pigment and has applications in photocatalytic materials.

Key Pointers

  • Chemical symbol: Ti.

  • Atomic number: 22.

  • Important minerals: Ilmenite and rutile.

  • Properties: Low density compared with many structural metals, high strength, corrosion resistance and good biocompatibility.

  • Applications: Aircraft, spacecraft, marine equipment, implants and chemical industries.

  • Titanium dioxide (TiO₂): Used in pigments, coatings and certain photocatalytic applications.

  • Indian relevance: Coastal mineral-sand deposits and the strategic importance of titanium-bearing minerals.

  • Challenges: Energy-intensive processing, production costs and supply-chain concentration.

UPSC focus: Critical minerals, strategic materials, advanced manufacturing and India's mineral-processing capabilities.
