Mixing and crystallization in suspensions
Chemical Engineering Science, 2000The influence of mixing on suspension crystallization is described from the starting point of a fully mixed system with mixed product withdrawal. An imperfect suspension, caused by less intensive mixing, is then introduced and the effects of imperfect suspension on suspension density distribution along the height and on crystal size distribution in the

A study on the mixed crystals of formula (1>x>0) has been carried out, using thermal analyses and x-ray diffraction on powder and single-crystal samples at different temperatures. It is shown that mixed crystals with have a transition from the paraelectric to the ferroelectric phase; decreases as the value of x increases.

The mixed suspension, mixed product removal crystallizer as a concept in crystallizer design
AIChE Journal, 1965AbstractSimultaneous population and mass balances have been solved together with a generalized form of nucleation‐growth rate kinetics to obtain the form of crystal size distribution (CSD) for several idealized modes of crystallizer operation, including seed crystal removal, product classification, arbitrary solids concentration, and staged vessels ...

Mixed Crystal Formation in High Polymers
Nature, 1947AN interpolymer of ethylene and vinyl alcohol (prepared by co-polymerization of vinyl acetate and ethylene followed by hydrolysis1) has been found to give a crystalline X-ray diffraction pattern different from those of either polythene or polyvinyl alcohol. The fibre repeat distance is 2.5 A., corresponding to a single hydrocarbon chain zigzag.

Mixing in continuous crystallizers
AIChE Journal, 1986AbstractThe review is concerned primarily with some aspects of mixing in continuous crystallizers and recognizes the central importance of the interplay between the mixing and crystallization (or precipitation) processes in the design and performance evaluation of industrial crystallizers.

Crystallization Kinetics of Calcium Lactate in a Mixed-Suspension-Mixed-Product Removal Crystallizer
Industrial & Engineering Chemistry Research, 1999Continuous crystallization of calcium lactate pentahydrate was investigated in a mixed-suspension-mixed-product removal crystallizer. Wide ranges of the mean residence time, relative supersaturation, and magma density were covered (40−215 min, 0.01−1.12, and 2−65 kg/m3, respectively). Crystal growth was found to be dependent on crystal size. The Abegg,

Mixed crystal deposition in an osteoarthritic joint
The Journal of Pathology, 1977The case of a 72-yr-old woman with osteoarthritis of the shoulder, is described. A mixture of crystals of hydroxyapatite and calcium pyrophosphate dihydrate was identified in the joint tissues using analytical electron microscopy and infra-red spectroscopy.

The simple example of phonons in a linear chain of atoms with substitutional disorder is reconsidered in order to determine the rearrangements of acoustic and localized mode branches with increasing concentration of light impurities. The coherent-potential approximation cannot be applies successfully to this problem.
