Ceramite is a form of heat and shock-resistant ceramic material that is widely used throughout the Imperium of Man. High-quality ceramite is used in the higher-quality types of Imperial armour, including Carapace Armour, Power Armour and Terminator Armour. Ceramite conducts almost no heat, making it especially heat-resistant and effective protection against energy-based weapons. Low-quality ceramite is used to mass-produce cheap Flak Armour for the Imperial Guard. An inexpensive and sturdy building material widely used across the Imperium consists of pulp wood formed around a core of low-grade ceramite. This material is used for the construction of low-cost prefabricated housing blocks on many Imperial Hive Worlds.
