    Super Fine 325 Mesh Fused Silica Powder for Quartz Nozzle ...
    High-grade ultra-fine fused silica powder is a high-purity (typically
    >99.5%is greater than 99.5 %
    >99.5%
    , often
    >99.9%is greater than 99.9 %
    >99.9%
    ), amorphous silicon dioxide (
    SiO2SiO sub 2
    SiO2
    ) material known for its extremely low thermal expansion, high chemical stability, and excellent electrical insulation. It is primarily used as a filler in semiconductor epoxy molding compounds (EMC), high-temperature refractories, precision casting, and coatings, with particle sizes ranging from a few microns up to 1250 mesh. 
    Key Characteristics and Applications 
    • High Purity & Low Expansion: Due to its amorphous nature, it offers exceptional dimensional stability under temperature changes, making it ideal for precision engineering and thermal shock resistance.
    • Semiconductor Industry: Ultra-fine powder (often
      ≤10μmis less than or equal to 10 mu m
      ≤10𝜇𝑚
      ) is used as a filler in IC packaging (EMC) and Copper Clad Laminates (CCL) for superior dielectric properties.
    • Refractory & Casting: Used in investment casting and as a refractory lining due to its high melting point and resistance to thermal shock.
    • Technical Specifications: Typical high-grade products boast low Fe₂O₃ and other impurities, high breakdown voltage (
      32−34KV/mm32 minus 34 KV/mm
      32−34KV/mm
      ), and fine, controlled particle size distribution.       
    Key Products and Suppliers 
    • Made-in-China.com: Offers high-purity (99.95%) micro-silica powder (
      3.5μm3.5 mu m
      3.5𝜇𝑚
      ).
    • Made-in-China.com: Specializes in 325-1250 mesh powder for refractory and electronic applications.
    • Caplinq: Supplies specialized, high-purity, ultra-fine quartz powder for electronic and semiconductor applications.
    • Alibaba.com: Features a wide range of customized fine fused silica for plastics and coatings. 
    These powders are produced by melting high-purity quartz (often sourced from locations like Donghai) at temperatures between 2000-2300°C to create amorphous silica glass.
