It absorbs water, for instance, although very slowly. This quality of porosity is not ideal for some applications, and the graphite material must be mixed, or “impregnated,” with other materials that alter the behavior of the material in special circumstances, such as in the presence of chemicals or extreme heat. Below are some of the more common impregnation types that...
