What this grade is for
Fine fluorspar powder for fluorine chemicals and metallurgical flux applications, available as wet or dried powder depending on the buyer requirement.
Powder is the most direct form for buyers that care about fast dissolution, controlled reaction, or tight feed preparation. It is the preferred form when the process depends on predictable chemistry and good mixing.
- Hydrofluoric acid and fluorine chemical feedstock.
- Metallurgical flux applications that require fine, process-ready material.
- Plants that want powder supplied wet or dried to match handling and storage constraints.
Published specification guidance
Use the table below as a buyer-facing starting point. Final chemistry, moisture, particle size, packaging, and inspection terms should still be confirmed in the sales contract.
Published powder ranges| Grade | CaF2 | Notes |
|---|
| Acid grade | >97% | Primary feed for fluorine chemicals and tighter purity control. |
| Met grade | 85% / 90% / 93% / 95% | Useful where the process values handling and chemistry together. |
| Dried powder moisture | <0.3% | For buyers that need lower residual moisture on arrival. |
Buyer checklist
Before you issue an RFQ, make the request precise enough for the plant and the logistics team to quote the same thing.
- Specify whether the cargo should be wet or dried.
- Confirm CaF2, SiO2, CaCO3, sulphur, phosphorus, and moisture together.
- State the intended process so the seller can match grade to use case.
- Confirm packing, inspection, and destination port before final quotation.
