| Abstract: |
| Precipitation of supersaturated caustic solution in the industrial Bayer process is usually seeded.The study of unseeded liquors is necessary for the determination of the critical stable nucleus size,interfacial tension,the order of nucleation and so on.Homogeneous nucleation of Al(OH)3 crystals from synthetic,optically clear caustic aluminate solutions has been investigated under isothermal,batch crystallization conditions with the application of a novel conductivity analyzer and conductometric detection c... |
