Aluminium Fluoride’s Type and Applications
Highassay offers metallurgical-grade, industrial-grade, and optical-grade Aluminum Fluoride. Please contact us if you require inquiries about Aluminum Fluoride raw material prices or related information.
- Highassay provides metallurgical-grade Aluminum Fluoride with a fluorine (F) content ≥60-62%.Furthermore, the control of major impurities such as Na, Si, Fe, P is relatively strict (Na≤4%; SiO₂+Fe₂O₃≤0.3%).This helps ensure stable electrolysis.
- Our metallurgical-grade Aluminum Fluoride is mainly used as an additive and electrolyte conditioner in electrolytic aluminum production. It plays a direct role in determining electrolytic efficiency and energy consumption levels during aluminum smelting.
- Metallurgical-grade Aluminum Fluoride raw materials are available in detailed grades, such as Special Grade 1, Special Grade 2, Grade 1, and Grade 2. Whatever grade you need, we can customize it exclusively for you.
- If you are an electrolytic aluminum producer, aluminum smelter, or aluminum product processing company and need to purchase Aluminum Fluoride raw materials or obtain the latest Aluminum Fluoride market price quotes, please contact us.
- Highassay’s industrial-grade Aluminum Fluoride(CAS 7784-18-1) contains ≥57-61% fluorine (F) with relatively lenient impurity requirements. It is widely used as a flux in ceramics/enamelware, a flux for non-ferrous metals, and a catalyst carrier.
- If you are a ceramics/enamelware manufacturer, adding our Aluminum Fluoride can effectively reduce the firing temperature by 15-30℃ and improve the surface gloss and strength of your products.
- If you are in the non-ferrous metal smelting industry and want to purify the melt, improve smelting purity, you can choose our Aluminum F
- Industrial-grade Aluminum Fluoride can also be used inalcohol fermentation inhibition, welding, and other fields.It is an excellent catalyst and auxiliary agent.
- Our optical-grade AluminumFluoride has a purity ≥99.9% (4N), with metallic impurities controlled below ppm, and is available in powder or granular/block form (1-6mm). It is primarily suitable for high-end manufacturing and R&D companies in optical components, optoelectronics, and other related fields.
- Optical-grade Aluminum Fluoride is a key material for optical coatings, fluoride optical glass, fluoride optical fibers, laser crystals and infrared windows, and optoelectronics and scientific research.
- Our high-purity Aluminum Fluoride can also be used as a low-refractive-index material in optical coatings, achieved through Aluminum Fluoride evaporation. It can be stably evaporated at 800-1000℃ in a vacuum environment.
- If you require customized optical-grade Aluminum Fluoride raw materials (specific purity, specific particle size, or special packaging), please do not hesitate to contact us as soon as possible.

Process types: Wet process Aluminum Fluoride (basically obsolete), dry process Aluminum Fluoride (the most widely used and technologically mature process), anhydrous Aluminum Fluoride (the most advanced third-generation technology).
Dry process Aluminum Fluoride is further divided into crude acid dry process (higher impurity content) and refined acid dry process (higher quality and beneficial for electrolytic aluminum).
Aluminum fluoride targets serve as source materials in the sputtering process, utilized to deposit extremely thin and uniform aluminum fluoride films onto product surfaces. They demand exceptionally high purity—typically ranging from 99.9% (3N) to 99.99% (4N)—and are typically fabricated in shapes such as circular discs or rectangles; they are widely employed within the optical and electronics industries.
The fluorosilicic acid method is a method for preparing Aluminum Fluoride.
The fluorosilicic acid process refers to the production of fluorosilicic acid from fluorine-containing waste gas generated during phosphate fertilizer production.Fluorosilicic acid reacts with aluminum hydroxide to produce Aluminum Fluoride.
The application of Aluminum Fluoride in the new energy field is maturing.It can be used as a modifier for lithium battery cathode materials; a solid electrolyte for sodium batteries; and a surface stabilizer for cathode materials, etc.
If you happen to be engaged in the research and development or production of new energy materials and need high-purity Aluminum Fluoride, please contact us for technical parameters and sample support.
