Product Description
 

Ultra-pure Hydrofluoric Acid

Ultra-pure hydrofluoric acid (HF) is characterized by its extremely low impurity levels, making it suitable for highly sensitive and demanding applications:
  1. Semiconductor Manufacturing
    Ultra-pure HF is a critical component in semiconductor processes, such as wet etching of silicon wafers. It is used in buffered oxide etches (BOE) and Wright etches to remove oxide layers and clean surfaces with high precision.
    Example Reaction:
    SiO2+4HFSiF4(g)+2H2O
  2. High-Purity Material Processing
    It is used to dissolve and process high-purity materials, such as quartz and silicon, for applications in electronics and optics. This ensures minimal contamination and high material purity.
  3. Analytical Chemistry
    Ultra-pure HF is used in laboratories for sample preparation, particularly for dissolving rock samples and other geological materials before elemental analysis.
    Example Application: Dissolving powdered rock samples to extract trace elements for analysis.
  4. Optics and Glass Processing
    It is used to etch and polish high-purity glass and crystal materials, ensuring high surface quality and minimal defects.
    Example Application: Etching and frosting of high-precision optical components.

Regular Hydrofluoric Acid

Regular hydrofluoric acid, with higher impurity levels, is used in a broader range of industrial applications where ultra-high purity is not required:
  1. Metal Processing and Pickling
    Regular HF is used in stainless steel pickling to remove oxide scales and impurities from metal surfaces. This process enhances the surface quality and corrosion resistance of metals.
    Example Application: Removing rust and oxide layers from stainless steel in industrial settings.
  2. Glass Etching
    It is used for etching and decorating glass products, such as glassware, architectural glass, and decorative items. The acid reacts with silicon dioxide in glass to create etched patterns.
    Example Reaction:
    SiO2+6HFH2SiF6+2H2O
  3. Rust Removal and Cleaning
    Dilute HF solutions are used in household and industrial cleaners to remove rust stains and mineral deposits. It is also used in car washes as a "wheel cleaner" to remove brake dust and rust.
    Example Application: Removing rust stains from ceramic tiles or automotive parts.
  4. Petroleum Refining
    Regular HF is used as a catalyst in the alkylation process in oil refineries. This process involves the reaction of isobutane with low-molecular-weight alkenes (e.g., propylene and butylene) to produce high-octane gasoline components.
    Example Application: Increasing the octane rating of gasoline in refineries.
  5. Production of Inorganic Fluorides
    Regular HF is used to produce a wide range of inorganic fluorides, such as sodium fluoride (NaF) and aluminum fluoride , which are essential in various industrial processes.
    Example Application: Production of cryolite  for aluminum smelting.

Summary

Ultra-pure hydrofluoric acid is primarily used in high-tech applications such as semiconductor manufacturing and analytical chemistry, where minimal impurities are critical. Regular hydrofluoric acid, with higher impurity levels, is used in broader industrial applications, including metal processing, glass etching, and petroleum refining.
