China's share in the global production of crystalline hafnium rods.

June 03, 2026
China's Share of Global Crystalline Hafnium Rod Production (2025-2026 Current Scope)
  • Global Annual Actual Total Production: 33–38 tons/year (High-purity formed crystal rods, excluding hafnium sponge and hafnium oxide)
  • China's Annual Production: 19–23 tons/year
I. Total Production Share: 55%–62%, the World's Largest Producer of Crystalline Hafnium Rods
  1. Standard Adopted Scope: Around 58% (Industry-standard data from SMM / Rare Metals Branch)
    • Combined overseas capacity: 14–16 tons/year (from US ATI + JP Tech US plant, France Orano, and Russia ChMZ).
    • Domestic mass production capacity: Approximately 22 tons. Of this, CNNC's 15-ton capacity is定向 (allocated) for domestic nuclear power and is not exported; market-oriented external sales of crystalline hafnium amount to 10–12 tons/year.
  2. Breakdown by Purity Grade
    • 3N–4N Industrial/Aviation Grade Crystalline Hafnium Rods: China accounts for 65%–70% of the global total (absolute dominance), serving as the main export specification from China.
    • 5N Ultra-High Purity Single Crystals (Semiconductor targets, high-end nuclear power): China accounts for 32%–38% globally. About 60% of the production capacity for high-end single crystals remains in the US, France, and Japan, representing a domestic shortcoming.
II. Detailed Capacity of Other Global Production Regions (Remaining 38%–45%)
  1. United States (20%): 7–8 tons/year. ATI and JP-Tech's New Jersey plant, focusing on 5N single crystals and nuclear-grade hafnium rods for domestic use + semiconductor imports from Japan, South Korea, and Taiwan.
  2. France Orano (13%): 4.5–5 tons/year. For European nuclear power and Airbus aerospace engines.
  3. Russia (7%): 2.5 tons/year. Rosatom for military and nuclear power use, with very little external sales.
  4. Japan + Others (5%): 1.5–2 tons/year. Small-batch crystal rod processing by Sumitomo, with raw materials purchased externally as crude hafnium.
III. Two Easily Confused Scopes (Key Distinction: Crystalline Hafnium ≠ Hafnium Sponge)
  1. All Categories of Metallic Hafnium (Total of sponge + hafnium ingots + crystal rods): China accounts for 70%–75% of global crude hafnium production (US investment bank scope). This data includes crude hafnium raw materials and is not equivalent to crystalline hafnium rods.
  2. Hafnium Oxide Powder: China accounts for around 40% globally. This figure is expected to rise annually after Sanxiang Advanced Materials expands production, and it belongs to a different product form than crystalline hafnium rods.
IV. Export vs. Domestic Use Breakdown (Affecting the Effective Share of External Sales)
Within China's total crystalline hafnium production:
