Low-sodium White Corundum

Low-Sodium White Corundum is a high-purity form of aluminum oxide (Al₂O₃) with minimal sodium content. This type of white corundum is produced by the high-temperature fusion of bauxite in an electric arc furnace, resulting in a clean, abrasive material with excellent hardness and stability. It is valued for its consistent quality and is used in a range of industrial applications requiring a high degree of purity and low sodium levels.

  • Product Category: Abrasive & Material
  • Key Features:
  • High Purity: Contains minimal sodium impurities, ensuring high performance and reduced contamination in critical applications.
