xtelge
Xtëlge is a fictional crystalline material used in theoretical materials science discussions and in science fiction. In these contexts, xtelge is described as combining high strength, low density, and exceptional thermal and chemical stability, which would make it suitable for extreme-environment applications.
Its assumed structure is a layered, open-framework crystal with a close-packed lattice and covalent cross-links, sometimes
