Ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material.
Well handling liquid nitrogen is effing dangerous but you probably knew that i m assuming that you ve got it stored in a cylinder or similar and are pouring it out.
Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics especially advanced ceramics are compounds of metallic elements and carbon nitrogen or sulfur.
Observe that it snaps in a brittle manner.
They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
Some elements such as carbon or silicon maybe considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension.
