Sodium Hexafluoroaluminate Granules, commonly known as cryolite, is an inorganic compound material with an important role in industrial production, mainly used in glass manufacturing industry, enamel industry and other industries.
VIMATERIAL’s Sodium Hexafluoroaluminate offer the advantages of high purity, stable physical and chemical properties, support for customisation of small-lot orders, sufficient stock, and short lead times. At the same time, we offer a full range of customisation services, whether it is a special pellet requirement or an innovative application exploration, you are welcome to communicate with us at any time. Please feel free to contact us for any of your needs.
Molecular Formula: Na₃AlF₆
Molecular weight: 209.94
Appearance: usually white or off-white particles, regular shape and uniform particle size.
Melting point: 1009°C
Crystal structure: Hexagonal crystal system, this crystal structure gives Na₃AlF₆ good chemical stability and specific ionic conductivity properties.
Aluminium electrolysis industry: It is an indispensable flux in the aluminium electrolysis process. It can significantly lower the melting point of alumina from about 2050°C to about 1000°C, which significantly reduces the energy consumption in the electrolysis process.
Glass manufacturing industry: as an additive in glass production, Na₃AlF₆ can reduce the melting temperature of glass, improve the clarification and homogenisation effect of glass, reduce the bubbles and impurities in glass, and improve the transparency and mechanical strength of glass.
Enamel industry: adding Na₃AlF₆ in enamel glaze can reduce the melting temperature of the glaze, promote the good combination of the glaze and the metal substrate, and improve the corrosion resistance, abrasion resistance and gloss of the enamel products.
Casting industry: when used in casting aluminium alloy, it can refine the grain, improve the casting performance and mechanical properties of aluminium alloy. It can effectively reduce the defects such as porosity and shrinkage in castings, and improve the dimensional accuracy and surface quality of castings.
Each batch of the product is thoroughly and meticulously tested for key indicators such as purity, particle size distribution, melting point and density. For any product that does not meet the quality standard, we immediately take strict isolation measures and strictly prohibit it from entering the next production or sales process.
Sodium Hexafluoroaluminate granules are packed in vacuum bottles followed by cartons or paper drums.
Sodium Hexafluoroaluminate granules should be stored in a dry, well-ventilated warehouse away from direct sunlight.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
