What this grade is for
Uniform fluorspar briquettes made from powder with an inorganic binder for controlled handling and furnace charging.
The source page emphasizes a 2.5 cm physical form and a low-sulphur, low-phosphorus metallurgical use case, so the buyer should quote shape and handling tolerance alongside grade.
- Metallurgical charging where consistent physical form helps plant operations.
- Buyers that need powder-based chemistry in a more manageable shape.
- Furnace and logistics teams that want more uniform handling than loose powder allows.
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 briquette grade ranges| Grade | CaF2 | Additional note |
|---|
| High-end | 90% / 95% | SiO2 <7% / <5%; CaCO3 <3%; S <0.1%. |
| Normal | 85% / 80% / 75% | SiO2 <13% / <16% / <20%; CaCO3 <3% / <5% / <5%; S <0.1%. |
| Physical form | Approx. 2.5 cm diameter | Designed to support controlled handling and furnace charging. |
Buyer checklist
Before you issue an RFQ, make the request precise enough for the plant and the logistics team to quote the same thing.
- State whether the briquettes will be charged into a furnace or used as a logistics-friendly alternative to powder.
- Confirm binder expectations and whether the buyer has any restrictions on inorganic binders.
- Specify the CaF2 range, size expectation, and target impurity limits.
- Ask for packing and breakage tolerance requirements before quoting.
