One common method to obtain pure samples of selenium is through the process of sublimation. Selenium can be heated to a temperature where it vaporizes and then allowed to condense back into a solid state in a clean container, resulting in a relatively pure sample. Further purification techniques such as recrystallization or distillation may also be employed to increase the purity of the sample.
