The Bridgman technique is a method used in materials science to create single crystals from molten materials. Named after physicist Percy Bridgman, this technique involves slowly cooling a molten substance in a controlled environment, allowing it to solidify into a uniform crystal structure. This process is crucial for producing high-quality crystals used in various applications, including electronics and optics. In the Bridgman technique, a crucible containing the molten material is moved through a temperature gradient. As the material cools, it begins to crystallize from one end to the other, promoting the growth of a single crystal. This method is particularly effective for materials that are difficult to crystallize using other techniques.
