99% Aluminum Fluoride (AlF₃), CAS No. 7784-18-1, is an inorganic fluoride primarily used in aluminum electrolysis and non-ferrous metal processing. Supplied as a white powder, it serves as a component and adjustment material in the molten electrolyte system used for primary aluminum production.

For the Russian market, this product is mainly intended for primary aluminum producers, non-ferrous metal smelters, metallurgical chemical distributors, and suppliers of aluminum electrolysis materials. Because shipments to Russia may involve long transit distances and extended storage periods, buyers should evaluate not only the AlF₃ content but also moisture, particle size, impurity composition, packaging integrity, and batch-specific COA data.

During primary aluminum production, alumina is dissolved in a molten electrolyte before electrolysis. Changes in electrolyte composition may affect its melting behavior, electrical conductivity, fluidity, and operating conditions inside the reduction cell.

Aluminum fluoride is used to adjust the electrolyte composition. However, Russian aluminum smelters should not select a product based only on the stated 99% AlF₃ content. Moisture, particle size, loss on ignition, and impurities may also affect material handling and process suitability.

The required addition rate is not universal. It should be determined by the smelter's technical team according to electrolyte analysis, cell design, operating temperature, and internal production standards.

The specified 99% AlF₃ content provides a clear basis for preliminary supplier evaluation, raw material calculations, and incoming quality inspection. It is suitable for aluminum electrolyte preparation and process adjustment where this assay level meets the smelter's technical requirements.

However, a 99% assay does not automatically indicate low moisture, low sodium, low iron, or low silica. Russian buyers should request a complete technical specification and verify critical impurities through a batch COA or third-party test report before placing bulk orders.

For shipments exposed to long-distance rail or road transportation and cold Russian winters, sealed moisture-resistant packaging is recommended. The material should be stored in a dry warehouse with the original packaging intact to reduce moisture ingress and changes in powder condition.

Primary Aluminum Production
Aluminum fluoride is primarily used to adjust the electrolyte system in primary aluminum production. It can be added according to electrolyte analysis and the operating condition of the reduction cells.

Russian aluminum producers commonly evaluate AlF₃ assay, moisture, loss on ignition, particle-size distribution, and impurities before approving a material. These parameters should be matched to the requirements of each smelter rather than generalized across all plants.

Non-Ferrous Metallurgy
AlF₃ may also be used in selected non-ferrous metallurgical, flux, and metal-processing systems. Suitability depends on the target metal, process formulation, melting temperature, and operating conditions.

Metallurgical Chemical Distribution
Russian and Eurasian Economic Union chemical distributors may supply aluminum fluoride to primary aluminum plants, metallurgical facilities, and industrial material processors.

Before importation, buyers should confirm the availability of a Russian-language safety data sheet, COA, packaging labels, shipping documents, and other documentation required for the intended transaction.

Ceramic and Enamel Processing
The supplied product catalogue also identifies ceramic and enamel production as possible application areas for aluminum fluoride, where it may function as a flux material. Nevertheless, aluminum smelting should remain the principal application focus of this product page for the Russian market.

In aluminum electrolysis, aluminum fluoride participates in regulating the composition of the molten electrolyte. An appropriate addition can help maintain the required physicochemical conditions for alumina dissolution and electrolytic operation.

Its exact dosage depends on electrolyte analysis, bath composition, cell temperature, operating condition, and plant-specific technical requirements. For this reason, a fixed addition rate should not be recommended without reviewing the actual process data.

No unsupported claims regarding energy savings, production increases, or efficiency improvements should be made unless they are supported by controlled plant data.

1. Verify the AlF₃ Assay
   The COA should state the actual AlF₃ test result, analytical method, production batch, and inspection date. Buyers should confirm whether "99%" is a typical value or a contractual minimum.
2. Review Critical Impurities
   Russian smelters may set limits for SiO₂, Fe₂O₃, Na₂O, and other impurities. These values are not provided in the current material and should therefore be confirmed before quotation or order approval.
3. Confirm Moisture and Loss on Ignition
   Moisture and loss on ignition may be important for material storage, pneumatic conveying, automatic feeding, and electrolyte control. Contract limits should be based on the customer's process requirements.
4. Match the Particle Size to the Feeding System
   Particle-size distribution can affect powder flow, conveying, dosing, and dispersion. The required range should be selected according to whether the smelter uses automatic feeding or manual addition.
5. Confirm Packaging for Russian Transportation
   For long-distance transportation, packaging should provide adequate moisture resistance and mechanical strength. The buyer should confirm bag weight, inner liner, pallet configuration, container loading, and labeling before shipment.
6. Check Russian Import Documentation
   Before bulk procurement, confirm the required Russian-language SDS, TDS, COA, packing list, certificate of origin, transport labeling, and applicable Eurasian Economic Union documentation.
7. Conduct Sample or Trial-Batch Testing
   For a new supplier, laboratory analysis or a controlled trial batch is recommended before long-term procurement. This helps verify chemical composition, powder condition, feeding behavior, and compatibility with the existing smelting process.

Is 99% aluminum fluoride suitable for every aluminum smelter?
Not necessarily. The 99% AlF₃ content is only one selection criterion. Each smelter may have different limits for moisture, particle size, silica, iron, sodium, and loss on ignition.

What is AlF₃ mainly used for in aluminum smelting?
It is mainly used to adjust the composition and operating properties of the molten electrolyte. The addition rate should be determined from electrolyte analysis and the smelter's internal process standards.

Is the product suitable for long-distance transportation to Russia?
Powdered aluminum fluoride can be transported over long distances when protected by sealed, moisture-resistant packaging. Bag strength, inner liners, pallet configuration, and transport labels should be confirmed before shipment.

Can Russian-language technical documents be provided?
Russian buyers generally request a Russian-language SDS, technical specification, and batch COA. Document availability should be confirmed with the supplier before placing an order.

Does 99% mean electronic grade or high-purity grade?
No. A 99% AlF₃ assay does not automatically qualify the product as electronic grade or ultra-high-purity grade. Grade classification also depends on moisture, particle size, loss on ignition, and individual impurity limits.
