  Cryolite, as the primary solvent in aluminum electrolysis production, plays a critically important role throughout the process. The quality of cryolite not only affects the purity of the electrolytically produced aluminum but also directly influences the efficiency and stability of the entire electrolysis operation. Therefore, accurate analysis and inspection of cryolite are essential to ensure optimal performance in aluminum production.

  It is well known that conventional materials typically analyze only the content of major impurities, whereas cryolite, as one of the primary raw materials used in electrolyte production, requires not only impurity analysis but also detailed examination of its key elements.

  During quality inspections, it is generally required to analyze both the content of main components and the levels of key impurities. The total analysis typically accounts for nearly 100% of the sample's composition, while also incorporating the concept of cation-anion balance to evaluate and validate the reasonableness of the analytical results.

  The cryolite manufacturer thus provides a solid basis for reasonably determining the content of the entire sample, helping to prevent quality incidents during the analysis process.
