    • PURPOSE: To produce alumina having uniform primary particles, by repeating the process comprising the heating of an aqueous solution containing seed aluminum hydroxide and the addition of an acid or alkali to the solution, and the process comprising the adjustment of the pH of the solution within a specific range by the addition of an Al-containing neutralizing agent.
      CONSTITUTION: An aqueous solution containing aluminum hydroxide forming a seed crystal is maintained at ≥50°C, and mixed with an acid (e.g. nitric acid, sulfuric acid, etc.) or an alkali (e.g. sodium hydroxide) free from precipitating ions under stirring to adjust the pH of the aqueous solution to ≤5 or ≥11. Thereafter, a neutralizing agent containing aluminum (e.g. sodium aluminate, aluminum sulfate, etc.) is added to the solution to adjust the pH to 6W11. The process of adding the acid or alkali and the process of adding the Al-containing neutralizing agent are repeated several times. The formation of secondary nucleus can be prevented, and stable alumina having improved sharpness of the pore size distribution can be obtained by this process.
