👉 The term "tetradymite" is a term used in nuclear physics and crystallography to describe a type of crystal structure that forms when two or more tetrahedra are aligned along a common axis. Tetradymites are also called twisted cubic, tetragonal, or octahedral crystals, depending on the orientation of the tetrahedra. Tetradymite is often used in materials science to model the behavior of materials at high temperatures and pressures, as
