  2. Crystal growth - Wikipedia

    en.wikipedia.org/wiki/Crystal_growth

    Crystal growth is a major stage of a crystallization process, and consists of the addition of new atoms, ions, or polymer strings into the characteristic arrangement ...

    en.wikipedia.org/wiki/File:Gallium_crystals.jpg

    Crystals of 99.999% gallium, grown and photographed by myself in February 2003. These particular crystals took about 45 minutes to grow, sitting in a plastic dish near a cool window. The lumpiness on the surface of these crystals is caused mainly by me shifting the dish around to monitor the progression of the crystal growth.

  4. Crystallization - Wikipedia

    en.wikipedia.org/wiki/Crystallization

    Time-lapse of growth of a citric acid crystal. The video covers an area of 2.0 by 1.5 mm and was captured over 7.2 min. The crystallization process consists of two major events, nucleation and crystal growth which are driven by thermodynamic properties as well as chemical properties.

  5. Kyropoulos method - Wikipedia

    en.wikipedia.org/wiki/Kyropoulos_method

    The Kyropoulos method, also known as the KY method or Kyropoulos technique, is a method of bulk crystal growth used to obtain single crystals.. The largest application of the Kyropoulos method is to grow large boules of single crystal sapphire used to produce substrates for the manufacture gallium nitride-based LEDs, and as a durable optical material.

  6. Crystal - Wikipedia

    en.wikipedia.org/wiki/Crystal

    A crystal's crystallographic forms are sets of possible faces of the crystal that are related by one of the symmetries of the crystal. For example, crystals of galena often take the shape of cubes, and the six faces of the cube belong to a crystallographic form that displays one of the symmetries of the isometric crystal system. Galena also ...

  8. Micro-pulling-down - Wikipedia

    en.wikipedia.org/wiki/Micro-pulling-down

    The micro-pulling-down (μ-PD) method is a crystal growth technique based on continuous transport of the melted substance through micro-channel(s) made in a crucible bottom. Continuous solidification of the melt is progressed on a liquid/solid interface positioned under the crucible.

  9. Flux method - Wikipedia

    en.wikipedia.org/wiki/Flux_method

    The flux method is a crystal growth method where starting materials are dissolved in a solvent (flux), and are precipitated out to form crystals of a desired compound. The flux lowers the melting point of the desired compound, analogous to a wet chemistry recrystallization. [1]
