WebThe flux method is an efficient liquid-phase crystal growth technique. It is expected to be one of the key technologies for the development of innovative inorganic materials in the future because it enables the production of high-quality crystals. WebThe principle of the process involves melting a finely powdered substance using an oxyhydrogen flame, and crystallising the melted droplets into a boule. The process is considered to be the founding step of modern industrial crystal growth technology, and remains in wide use to this day. [2] [3] History [ edit]
Webusually involves the well-established growth methods named after Bridgman, Czochralski, and Verneuil; zone melting, top-seeded solution growth (TSSG)/flux; recrystal-lization techniques; etc. The crystal growth from liquid phases plays the most important role. Each step of the growth process is affected by controlling the experimental WebThe Bridgman technique (also known as Bridgman-Stockbarger method) is one of the oldest techniques used for growing crystals. Similar to Czochralski technique, the Bridgman technique employs also a crystal growth from melt. In Bridgman technique the crucible containing the molten material is translated along the axis of a temperature gradient ...
