Low Sodium White Fused Alumina

Low sodium white fused alumina using high-quality low-sodium alumina, by the sodium removal process in the before and during arc furnace smelting process, and melting above 2000 in the electric arc furnace and cooling, the sodium(Na2O) content of low sodium white fused alumina is reduced to less than 0.1%, improving the white fused alumina melting point, density, bulk density, modulus of rupture(MOR), compressive strength, chemical stability, and hardness. It can meet the needs of special high-grade refractory materials, specific ceramic applications, and precision abrasives industries, etc.

Low Sodium White Fused Alumina Production Process

  1. Raw materials: Using the high-grade low-sodium Bayer industrial alumina powder
  2. Mixing: mix low-sodium alumina raw materials with boric acid, ammonium chloride, aluminium fluoride, and other additives, strictly by the formula ratio,
  3. Grinding: Add the mixed raw materials to a ceramic ball mill and grind for 2-4 hours
  4. Electric melting: Put the prepared mixed raw materials into the electric furnace, proceed high-temperature smelting during the temperature is strictly controlled at 2100℃-2300℃ degrees Celsius, the duration is 1-2 hours
  5. Cooling: Let the molten white fused alumina fully cool down, and use a specialised container to avoid contamination.
  6. Crushing: use a specialised crushing production line for processing, crushing, and screening
  7. Washing: use the pure water from the water filtration workshop to wash or acid-pickling the semi-finished products to remove impurities, and finally, dry
