Zirconium
Zircon sands feed ceramics and refractories; zirconium metal clads nuclear fuel rods.
Nuclear fuel cladding for the reactors increasingly contracted to power AI data centers; zirconia ceramics.

Zirconium: key questions
- Where is zirconium mined or produced?
- According to USGS 2025 data, the largest producers are Australia (33%), South Africa (23%) and Mozambique (13%) of world zircon concentrate mine production. China accounts for about 8%.
- Is zirconium a critical mineral?
- Zirconium appears on 6 of the 10 official lists we track (United States, China, Japan, South Korea, India, Australia).
- Is zirconium in short supply?
- Our supply status: Adequate. null
- Why does zirconium matter for AI infrastructure?
