Aluminum fluoride

      

    Molecular formula: AlF3
    Grade: Industrial
    Appearance: Sand-like
    Application: Electrolytic Aluminum
    CAS Number: 7784-18-1
    Colors: White, Off- White
    Uses: Used to reduce the melting temperature of electrolyte in the aluminum electrolysis industry And to improve electrical conductivity, it is used as a flux for non-ferrous metals, as a flux and component of ceramic glaze and enamel glaze, and as an inhibitor of secondary fermentation in essential oil production. Used as a side fermentation inhibitor in alcohol production. Used in welding fluids in metal welding, used to make optical lenses. It is also used as a catalyst for organic synthesis and a raw material for artificial cryolite.
    Physical and chemical properties: Aluminum fluoride products can be divided into anhydrous aluminum fluoride, dry aluminum fluoride and wet aluminum fluoride. The main content of anhydrous aluminum fluoride is high, and the magazine content is extremely low. It can effectively adjust the electrolyte molecular ratio and reduce the hydrolysis loss in aluminum electrolysis production. It is beneficial to improve the quality of aluminum ingots and reduce production costs. It represents the role of aluminum fluoride products. Direction of development.
    Packing specification: Laminated plastic woven bag lined with plastic film double-layer packaging, net weight of each bag is 25Kg, 50Kg, or according to customer requirements.
    Technical requirements: GB/T 4292-2007
