Preparing Sample Materials by Cryogenic Grinding. Cryogenic or cold grinding has proved to be the most ideal solution for these types of samples. This involves grinding aids such as dry ice (78 °C) or liquid nitrogen (196 °C) that are capable of embrittling the sample by cooling and making it break more easily.

Cryogenic Grinding Cryogenic grinding can achieve a very fine level of grind as most hardy materials tend to become brittle when cooled with liquid nitrogen. This is accomplished by techniques called cryogenic grinding. Cryogenic processing refers to the use of liquid nitrogen (−196°C) to freeze tire chips prior to size reduction. The rubber is immersed in liquid nitrogen to reduce the temperature of the tire chip. .
