Aluminum Fluoride (AlF₃) Product Introduction

CAS No.: 7784-18-1
Molecular Formula: AlF₃
Appearance: White crystalline powder/granules, odorless; Anhydrous aluminum fluoride is chemically stable, sparingly soluble in water, acids, and alkalis, insoluble in most organic solvents, and can sublimate at high temperatures without decomposition. It can partially hydrolyze into hydrogen fluoride and aluminum oxide upon contact with water vapor at 300~400℃.

Product Grades: Industrial anhydrous aluminum fluoride (mainstream), high-purity aluminum fluoride, aluminum fluoride trihydrate.

✅ Production Process
The mainstream processes are divided into dry process (modern mainstream, high quality) and wet process:

Dry Process (Refined Acid Dry Process): Using fluorite powder, concentrated sulfuric acid, and aluminum hydroxide as raw materials; fluorite reacts with sulfuric acid to generate hydrogen fluoride gas, which directly reacts with aluminum hydroxide in a high-temperature fluidized bed to produce anhydrous aluminum fluoride in one step.

✅Advantages: Low moisture content, high purity, good fluidity, and few impurities, making it the preferred process for large-scale electrolytic aluminum enterprises, with superior energy consumption and environmental performance.

Wet Process: Hydrofluoric acid reacts with aluminum hydroxide in the liquid phase, first crystallizing to form aluminum fluoride trihydrate, then filtering and high-temperature calcination to obtain anhydrous aluminum fluoride.

Characteristics: Low equipment investment, but the product has a higher moisture content and produces more wastewater; mostly used in ceramics and general enamel.

✅Application Areas:

Electrolytic Aluminum Industry: Core flux for electrolytic cell electrolytes, lowering the system's melting point, increasing electrolyte conductivity, reducing electrolysis energy consumption, and stabilizing electrolysis conditions; an essential raw material for primary aluminum production.

Ceramics, Enamel, Glass: Flux and opacifier for glazes, lowering firing temperature, improving glaze surface smoothness, and reducing pinholes and glaze peeling defects; can be used in the preparation of optical fluorinated glass to control optical refractive index.

Non-ferrous metallurgy: Smelting and brazing flux for non-ferrous metals such as copper and magnesium; removal of oxide scale from metal surfaces; preparation of fluoride raw materials such as cryolite and fluoroaluminates.

Other fields: Catalysts for organofluorine synthesis; by-fermentation inhibitors in alcoholic fermentation industries; raw materials for specialty electronics and fine fluorochemicals.

✅ Packaging specifications: 25kg/bag, lined with PE moisture-proof film, outer layer of laminated woven bag (25kg iron drum packaging is also available upon request); store in a sealed, dry place, protected from moisture, and avoid mixing with strong acids.
