      Alias: Sodium hexafluoroaluminate; Sodium aluminum fluoride
      Molecular formula: Na3AlF6
      Grade: Industrial grade
      Appearance: powder, sand
      Applications: Electrolytic aluminum, abrasive and grinding tool, glass, enamel, ceramics, pesticides
      CAS Number: 13775-53-6; 15096-52-3
      Colors: white

      Uses: Specially used in the high-end abrasive and grinding tool industry, metal flux industry, etc.
      Physical and chemical properties: white crystalline powder. PH value between 3.5-8 (adjustable), particle size of 40-12000 mesh (150μm ~ 1μm), the proportion of 2.95-3.01g / cm3 , a melting point of 920 ℃, insoluble in anhydrous hydrogen fluoride, water-soluble
      Features :
      1. The main content (F, Al, Na) can reach 98.5% or more, and the impurity content is low.
      2. The various indicators are stable, the particle size distribution is uniform, and the crystal surface is smooth and clean, which helps to better combine with the abrasive. 3. It can improve the grinding efficiency and grinding ratio of abrasive tools.
      4. Improve the wear resistance of abrasive tools and extend the service life of abrasive tools.
      5. It helps to better take away the grinding heat during the grinding process.
