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.

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 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 low temperature solutions

Journal of Crystal Growth, 1981
Abstract In crystal growth from solution, Fick's law of diffusion normally does not hold and convective transport must be taken into account. Convection (free and forced), which keeps a crystal growing, is given some attention. The prediction of a growth mechanism from thermodynamics seems still difficult; however, it is shown that the growth rate is

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

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 ...

Top‐Seeded Solution Growth of Monomethylurea Single Crystals

Crystal Research and Technology, 1997
AbstractIt was previously reported on the growth of monomethylurea (NMU) single crystals from methanol solution by a mechanical limitation‐direction (MLD) technique in which long (100) oriented seeds, capped on their extremities, were employed. The crystals obtained by this technique, in spite of their good structural and optical quality, presented ...

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.
