- In crystallography, the
tetragonal crystal system is one of the 7
crystal systems.
Tetragonal crystal lattices result from
stretching a
cubic lattice...
- In geometry, a
tetragonal trapezohedron, or deltohedron, is the
second in an
infinite series of trapezohedra,
which are dual to the antiprisms. It has...
- high thermostability.
Three phases are known:
monoclinic below 1170 °C,
tetragonal between 1170 °C and 2370 °C, and
cubic above 2370 °C. The
trend is for...

Unlike the
tetragonal disphenoid, the
rhombic disphenoid has no
reflection symmetry, so it is chiral. Both
tetragonal disphenoids and rhombic...
