1 M sodium citrate, pH 3. Reactant Diffusion This is a less-common technique, in which solutions of reactant are allowed to diffuse into each other.
Make sure the Growing Crystal from Solutions does not touch the bottom or the sides of the glass, or your crystals will not form right! Therefore it is worthwhile spending time on improving the quality of your crystals.
a disposable plastic or paper cup• Deionised water DI-water Stock solutions The following aqueous stock solutions should be prepared in advance by the teacher:• He is the scientific officer of the NCCR and is responsible for education, technology transfer and programme coordination.
Ideal solvents for this technique are those in which your compound displays high solubility at high temperature and low solubility at low temperature.
As soon as I find out how to distribute them you are first in line.alum, sugar, salt to the solvent usually water, although some recipes may call for other solvents. Disadvantages: Needs a lot of material, starts with almost saturated solution, which can lead to too much nucleadtion, not so good for air-sensitive compounds. For the intermediate Ge content, the grown crystals were polycrystals.
X-ray measurements can be made either directly from school samples, or, if shipment is a problem, by reproducing the optimised crystallisation conditions found in your class and measuring those crystals. Heating of the crucible can be accomplished Growing Crystal from Solutions a resistance-heated furnace, radiofrequency induction heating using the crucible as a susceptor, or laser heating.
A small gradient will induce a slow current which will not inhibit crystal growth as much as a large current. Remove the seed quickly and add more alum to the solution, filtering off any undissolved particles.
Clockwise from top left: Crystallization dish, disposable vials, petri dish, and watch glass. Disposable vials allow some control over the rate of evaporation as the polyethylene lids are easy to pierce with a needle.

All groups can use the same stock solutions.
Although the feasibility of these methods was demonstrated, its use for production is limited owing to technical and material problems preventing a high yield.
