What is the Czochralski process?
The Czochralski process is a method for the production of individual crystals, solid pieces of material with even crystal matrix. Such crystals are well used in the construction of electronic ingredients, as well as in scientific research and a number of other applications where a high -quality crystal with a uniform matrix is needed. For example, jewelers can use the Czochralski process to create high -performance gems for their projects, as well as research facilities with the need for materials such as Diamond, can grow in the laboratory with this technique. It begins with melting the ingredients in a cup capable of tolerating extremely high temperatures. It is usually placed in a closed furnace with a very accurate temperature control. High control is critical because the process fails if the mixture is too hot or too cold and very exsensors ACT can be placed in several places to monitor temperature changes.
When the mixture is heated by any dopant and other accessories that may be necessary, the technician can carefully reduce the seminal crystal rod. This is usually done by means of mechanical equipment rather than hand. Furthermore, the rod is carefully and very slowly withdrawn because the mixture forms a solid matrix around the seed crystal. The final result of the Czochralski process should be a solid material protocol, with some remnants at the bottom of the crucible.
In the settings, where the temperature rises too high, the seeds can melt. The introduction of a crystal at low temperatures can cause premature crystallization of the entire crucible content, complete with cracks, turning lines and other impurities. This process is slow; The withdrawal of the seed crystal is measured in millimeters. Careful control required during the Czochralski process can bring high quality crystals with a minimum of dirt.
production costs may depend on the necessary raw materials and crystal size. Larger crystals are more demanding to growand require a greater degree of control. Some raw components are very expensive. Czochralski process crystals are chemically identical to natural formations, but have much higher quality and reliability. This is usually desirable in settings, such as laboratories and electronics manufacturers, but jewelers sometimes have difficulty selling laboratory stones due to consumers' preference for natural stones.
