WebIn 1916, Jan Czochralski (1885 -1953), a Polish chemist, developed a new method for synthesizing rubies. Known as crystal pulling, this is a fast and effective method of producing nearly flawless stones from a melt. When … WebA Czochralski crystal pulling apparatus for carrying out the Czochralski crystal pulling process is provided with a reflecting plate for reflecting radiation heat radiated from the surface of a molten material contained in a crucible toward a contact region of the surface of the molten material contiguous with the wall of the crucible to heat the molten material in …

WebJan 31, 2011 · The micro-pulling-down technique is a crystal growth method that has been mostly developed since 1992. The general scheme of the growth system is relatively simple: the melt (oxide, fluoride, metal) residing in a crucible is transported in downward through microcapillary channel (s) made in the bottom of the crucible. http://www.jiwaji.edu/pdf/ecourse/physics/M.Sc.%20Physics%20on%20Crystal%20Growth%20Technique.pdf WebPolycrystalline solids are typically produced by this method unless special techniques are employed. In any case, the temperature must be controlled carefully. Large crystals can … t-shirt smiley
