Study on the Control of Super-Fine Aluminum Hydroxide Particle Size from Sodium Aluminate Solutions

Article Preview

Abstract:

The super-fine aluminum hydroxide was prepared by crystal seed precipitation from sodium aluminate solutions in this study. The influence of NaOH concentration, [NaO/[Al (OH)3] molar ratio, precipitation temperature, and precipitation time on the particle size of super-fine aluminum hydroxide was investigated. The results show that the optimum conditions were: NaOH concentration be 180 g/L, [NaO/[Al (OH)3] molar ratio be 1.15, precipitation temperature be 40°C, and precipitation time be 26 h.
