with the increment of particle size, and the critical nucleus sizes increase with the rise of alkali concentration, caustic ratio and precipitation temperature. The results also imply that the presence of small particles in seeded precipitation system is an important factor to limit the depth of precipitation. Key words: Bayer liquor; Al(OH)3; interfacial property; solubility; critical nucleus size 1......
