Growth of Nb3Sn crystals by top seeded solution growth

Journal of Crystal Growth, 1983
Abstract Nb 3 Sn crystals were grown by top seeded solution growth using the oscillating temperature technique. The maximum size obtained on the seed (Nb wire) was about 0.5×0.3×1 mm 3 after a 6 day run. The surface microtopograph was examined using differential interference and/or phase-contrast microscopy.

Ice crystal growth in supercooled solution

International Journal of Refrigeration, 2002
Study on the crystal growth of ice in water-ethyleneglycol solution was carried out, experimentally. The ice crystal, which was seeded on top of the capillary tube, propagated inside the tube slowly and began to grow freely at the tip of the tube in subcooled solution.

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

Crystal growth from solutions in low gravity

15th Aerospace Sciences Meeting, 1977
An experiment performed during the Apollo-Soyuz flight investigated a novel process for growing single crystals from solutions. In zero gravity, reactant solutions were allowed to diffuse slowly toward each other through a region of pure solvent in which they underwent a chemical reaction to form crystals of an insoluble material.

A Crystallizer for the Investigation of Conditions of Growth of Single Crystals from Solutions

Kristall und Technik, 1971
AbstractThe crystallizer of the Walker‐Kohman type for isotherm growing of single crystals from solutions is described which has been designed to provide the maintenance of constant conditions of crystallization chosen in advance and the investigation of the influence of these conditions on the resulting structural regularity of the crystals as grown ...

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.

Modelling of crystal growth in multicomponent solutions

2003
Abstract The crystal growth model was derived from Maxwell-Stefan equations for the diffusioncontrolled growth regime. As a model system, the ternary potassium dihydrogen phosphate (crystallizing substance)-water (solvent)-urea (foreign substance) system was employed.

On the growth rate of crystals from solution

Journal of Crystal Growth, 1968
Abstract Both a rigorous calculation and an approximate calculation of the crystal growth velocity as a function of time have been generated for the growth of a crystal layer from solution wherein the solution has been subjected to a variable cooling rate.

Partition in the growth of solid solution crystals

Materials Research Bulletin, 1966
Abstract A description of steady-state partition is applied to 3d ions in the crystal growth of sulfates and fluosilicates. Preliminary results are given for 4f ions in fluorite. Solubility order in a given host shows the influence of CFSE (crystal field stabilization energy).

Crystal growth of CuGaSe2 from In solutions

Journal of Crystal Growth, 1987
Abstract The phase relations of a CuGaSe 2 —In pseudobinary system have been studied and the conditions of preparation of the solid phase having the chalcopyrite crystal structure were obtained. On the basis of the data, CuGaSe 2 crystals were grown from In solutions, and their properties were examined.
