Sucrose crystal growth. I. Rate of crystal growth in pure solutions

Australian Journal of Chemistry, 1967
A method is described for the measurement of rate of growth of sucrose crystals from aqueous solutions under controlled conditions of temperature, super-saturation, and relative velocity of the solution with respect to the crystal. The effects of these parameters on sucrose crystal growth rates in pure sucrose solutions are reported. The results can be

The growth of crystals from the boiling solution

Journal of Crystal Growth, 1972
Abstract A novel technique is described in which crystals have been grown from solutions at their boiling point. The technique permits accurate control of solvent loss, permits seeding, and avoids undesirable nucleation at the liquid-gas interface. Various iodates have been grown from boiling water and from boiling concentrated nitric acid.

Solution growth of vanillin single crystals

Materials Letters, 1991
Single crystals of vanillin were grown by the solution growth method. Vanillin was observed to be very anisotropic, and crystal morphology was strongly dependent on solvent. Crystals grew in needle morphology in pure methanol and ethanol, and in plate morphology in pure chloroform. A mixture of methanol and chloroform was found to be a suitable solvent

Solution growth of sodium azide crystals

Materials Research Bulletin, 1970
Abstract A growth method is described which retards hydrolysis of the azide and yields large crystals of high purity. Aqueous and non-aqueous growth systems are evaluated.

Solution growth of magnesium oxide crystals

Journal of Crystal Growth, 1969
Abstract The growth of magnesia by both hydrothermal and fluxed-melt techniques has been achieved. In the latter process, growth of an appreciable volume of material on a seed crystal was obtained by temperature gradient transport. The quality of the product was generally superior to that of the staring material, although microscopic inclusions of ...

Solution growth CdGeP2 crystals and layers

Journal of Crystal Growth, 1980
Abstract CdGeP 2 crystals and layers have been grown from molten bismuth. Crystals with the size of 12 × 4 × 3 mm 3 were produced. Preliminary attempts have been made to obtain CdGeP 2 layers on germanium substrates. It was found that deposition of CdGeP 2 layers is possible, but without epitaxial growth.

Crystal Growth from Transparent Solution - Two Methods to Study Crystal Growth and Hydrodynamics of the Solution at a Time

1989
The subject of this paper deals with applications of holography in crystal growth from transparent solutions. The method may be easily applied also to crystal growth from transparent melt, but no experiment has been done up to now in this field.

Kinetics of crystal growth from solution

Journal of Crystal Growth, 1968
Abstract The crystallization of a number of sparingly soluble salts on the addition of seed crystals to stable supersaturated solutions has been followed by conductivity measurements, by analysis, and by microscopic observation of the growing crystals.

Ice Crystal Growth in Aqueous Solutions

1987
Causes and mechanisms of cryo-injury are generally multifacetted and may be of thermal, mechanical, chemical and electrical nature. For understanding the effects of ice formation on biological cells it is necessary to first obtain an exact knowledge of the ice formation process itself.

On the mechanism of crystal growth from solutions

Journal of Crystal Growth, 1998
Abstract The published experimental data on the supersaturation and temperature dependence of face growth rates R , inclinations p of hillocks and displacement velocity v of steps on the (1 0 0) and (1 0 1) faces of ammonium dihydrogen phosphate and the (0 0 1) face of L-arginine chloride monohydrate single crystals are analysed.
