Flux method crystal growth
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] WebThe temperature gradient growth (TGG) method is in fact a variety of the widely used method of crystal growth from solution in melt. For growing diamond, this method was originally developed and applied by the GE scientists, who first produced large diamond crystals weighting about one metric carat (200 mg, 5–6 mm across) in the early 1970s ...
