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 infantry, vehicle and aircraft armour, including Carapace Armour, Power Armour and Terminator Armour. High-quality Ceramite is also used to provide additional protection for the vehicles of the Adeptus Astartes. Ceramite is capable of absorbing and dissipating even the most extreme thermal and directed-energy attacks, and conducts many other forms of electromagnetic radiation in such a way as to disperse it across a wide area. This makes Ceramite especially effective at providing protection against directed-energy and particle-based weapons. Lower-quality Ceramite is also used to mass-produce cheap Flak Armour for the Astra Militarum. 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 the low-cost prefabricated housing blocks prevalent on many Imperial Hive Worlds.
