Zirconium was discovered in 1789 by the German chemist Martin Heinrich Klaproth while studying the gemstone zircon. The pure metal was later isolated in 1824 by the Swedish chemist Jöns Jakob Berzelius.
Zirconium is mainly found in the minerals zircon (ZrSiO₄) and baddeleyite (ZrO₂). Large deposits occur in Australia, South Africa, India and Brazil.

Zirconium is used in nuclear reactors, jet engines, chemical plants, surgical implants, ceramics and corrosion-resistant equipment.
Titanium, Hafnium, Oxygen and Niobium
Although zirconium resists most chemicals, it reacts with hydrofluoric acid and can burn as a fine powder in air at high temperatures.

Zirconium combines exceptional corrosion resistance with a very low tendency to absorb neutrons, making it one of the most important metals used in nuclear reactors.
Zirconium alloys are used to make the protective tubes that surround nuclear fuel because they are strong, corrosion-resistant and allow neutrons to pass through efficiently.
Zirconium alloys are widely used as fuel cladding in nuclear reactors. Their unique ability to resist corrosion while absorbing very few neutrons makes them ideal for safely containing nuclear fuel.
Zirconium dioxide can be transformed into cubic zirconia, a sparkling gemstone widely used in jewellery as a brilliant diamond substitute because of its clarity and durability.
Zirconia ceramics are used to manufacture dental crowns, implants and artificial joints because they are strong, biocompatible and resistant to wear.
Zirconium alloys are used in aerospace and high-temperature engineering because they retain strength while resisting heat and corrosion in demanding environments.
Tiny zircon crystals have survived for billions of years, carrying evidence from the earliest chapter of Earth's history. By studying these ancient minerals, scientists learn about the formation of continents, the presence of early water and the evolution of our planet. Few elements connect modern nuclear technology with Earth's ancient past as beautifully as zirconium.
Researchers are developing zirconium-based materials for advanced nuclear reactors, hydrogen storage, biomedical implants, high-performance ceramics and next-generation energy systems.
Zirconium is produced inside stars through neutron-capture nucleosynthesis. Tiny zircon crystals found on Earth are among the oldest known minerals, preserving clues about our planet's earliest history.
Some zircon crystals are more than 4.3 billion years old. They are among the oldest surviving materials on Earth and help scientists understand the conditions of our young planet.
