From fluorotitanate salt to aluminum master alloy
Potassium titanium fluoride is the titanium source in a foundry chain we supply end to end. Every downstream stage below is a product on this site — follow the chain to the grade you actually need.
Co-applications: used directly as a flux agent in aluminum melt treatment, and in metal surface phosphating formulations outside the alloying route.
What K₂TiF₆ is used for
Potassium titanium fluoride is a white to off-white crystalline powder, the dipotassium salt of the hexafluorotitanate(IV) anion [TiF₆]²⁻. It is produced from a titanium-bearing feedstock reacted with hydrofluoric acid and a potassium salt, and supplied as a stable, non-flammable solid.
Its largest industrial use is as the titanium source for Al-Ti and Al-Ti-B master alloys and grain refiner tablets, used to control grain structure in cast aluminum. Alongside this it serves as a flux agent in metal casting, a component of metal surface phosphating treatments, a reagent in the manufacture of metallic titanium and titanic acid, an analytical reagent, and an additive in select flame-retardant formulations.

Importing into the United States
Potassium titanium fluoride is a TSCA-regulated chemical substance. Under TSCA section 13 the importer of record, or its authorised agent, must certify to US Customs and Border Protection that each shipment either complies with TSCA or is not subject to it. We confirm the substance's TSCA Inventory status and agree in writing who files that certification before the first consignment moves.
Which party carries that duty follows the Incoterm. On FOB, CFR or CIF terms it is usually the US buyer; on DDP terms it can be the seller or its agent. Safety data sheets and labels are supplied to OSHA's updated Hazard Communication Standard, and UN 3288 transport documentation and labelling is applied before booking.
| Item | How it works |
|---|---|
| Delivery points | Any nominated US plant, warehouse or port of discharge |
| Incoterms quoted | FOB · CFR · CIF · DDP |
| Importer of record | Agreed in writing before the first shipment |
| TSCA certification | Section 13 positive certification filed at entry |
| Documentation | Batch COA, SDS, packing list, certificate of origin |
| Pack formats | Bags, FIBC jumbo bags or drums |
Note: regional coverage describes where we deliver, not where we hold inventory. Lead time depends on producer scheduling and ocean transit to your nominated US port — we confirm both in the quotation.
How we supply potassium titanium fluoride
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. Titanium content, particle size and moisture decide whether a lot performs cleanly in master-alloy production or flux chemistry — that shapes how we select producers on this line.
We place your order with whichever qualified producer best matches your required grade, your price point and your delivery window, and confirm US import requirements before booking.
We keep a second qualified source on this line, so a single-plant disruption never becomes your production problem.

Reacts with acids to release HF — handle accordingly
Potassium titanium fluoride is a stable, non-flammable solid that liberates hydrogen fluoride gas on contact with strong acids. The summary below is orientation only — the safety data sheet supplied with your specific batch is the authoritative document.
Classified hazards
H302Harmful if swallowed.H315Causes skin irritation.H317May cause an allergic skin reaction.H318Causes serious eye damage.H335May cause respiratory irritation.
Acid contact. Contact with strong acids liberates hydrogen fluoride, a highly toxic and corrosive gas. The product is incompatible with oxidizing agents. Confirm your site's obligations with your EHS team.
Storage
Store in closed, tightly sealed containers in a cool, dry, well-ventilated area away from strong acids, oxidizing agents and foodstuffs. The product is stable under normal conditions and is not flammable.
Handling
Handle with local exhaust ventilation and dust control. Avoid inhaling dust, wear eye and skin protection, and keep washings out of drains given the risk of hydrogen fluoride generation on acid contact.

We verify documentation before dispatch so there are no surprises at your incoming-goods bench.
Specification agreed
Purity, titanium content and moisture confirmed against your process requirement before order placement.
Producer batch testing
The producing plant tests each batch against the agreed specification before release.
Documentation review
COA, SDS, TSCA certification data and UN 3288 transport paperwork checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing batch, with full chain-of-custody records on request.
How it is made
Potassium titanium fluoride is produced by reacting hydrofluoric acid with a titanium-bearing feedstock in the presence of a potassium salt, crystallising the K₂TiF₆ double salt out of the resulting fluorotitanic acid solution.
The crystallised salt is filtered, washed and dried to the commercial powder grade, then checked against titanium content, purity and moisture before release.
Downstream, the product is reacted with molten aluminum to introduce titanium into Al-Ti and Al-Ti-B master alloys, which are further processed into grain refiner tablets and alloying tablets for aluminum casting.
We do not publish operating process parameters here; this is background only. Full technical documentation accompanies every shipment, and any process-specific detail you need is best confirmed directly with our technical desk.
