摘要:
AbstractApplication of a microcomputer control system to programme the dosage rate during a batch precipitation is described. The technique is tested with the drowning‐out precipitation of potassium sulphate from aqueous solution using acetone. Programmed dosage controls the transient supersaturation and crystal growth rate thereby improving the product crystal size distribution. A consequent improvement in filtrability characteristics is also indicate

摘要:
AbstractThe article presents an analysis into agglomeration during KCl vacuum crystallization. The theoretical and experimental investigations into the mechanism of agglomeration during mass crystallization result in an extension of the growth phenomena within the known model equations. The basis for this is essentially constituted by the collision model concepts of the theory of floculation in disperse systems. The parameters derived from the microprocess analysis (energy dissipation, content of solids, growth rate of individual grains) lead to model equations which are confirmed by laboratory and test trials.

摘要:
AbstractSeven pentagonal point groups are considered to be compatible with the local symmetry of crystal structures and important when interpreting the transition from precrystalline and quasicrystalline to true crystalline states. Clusters of fivefold symmetry seem to be stable balancing fourfold and sixfold symmetries. Together with clusters with other symmetry they play perhaps a significant role in the nucleation process and the ensuing growth of the crystals.

摘要:
AbstractOxygen‐plasma‐treated thin thermal SiO2films (15–100 nm) have been studied by Reflection High Energy Electron Diffraction (RHEED). The presence of unconventional type microcrystalline regions (not only tetrahedrally coordinated) in the amorphous matrix of the oxides is established. Thinner oxides (15–50 nm) are more sensitive to the plasma action. In general, oxygen plasma leads to an additional deformation and decomposition of the initial crystalline forms and causes a degradation of the electrical parameters of the
