Fluorspar and hydrofluoric acid (HF) feedstock
BOTTLENECKChinese concentration of acid-grade fluorspar gives pricing power over the sole upstream fluorine source for chip etch gases and wet chemicals.
Acid-grade fluorspar (CaF2) is mined and reacted with sulphuric acid to make anhydrous hydrofluoric acid. This is the sole upstream fluorine source for etch gases and fab wet chemicals used in chip manufacturing. Chinese concentration of fluorspar gives upstream pricing power; acid-grade and anhydrous HF command premiums over metallurgical grades.
What the evidence shows
New entrants face a 12–18‑month qualification gauntlet with semiconductor end‑users, requiring multiple sampling rounds and on‑tool testing.
