- In crystallography, the
tetragonal crystal system is one of the 7
crystal systems.
Tetragonal crystal lattices result from
stretching a
cubic lattice...
-
common lattice system are
combined into a
crystal family. The
seven crystal systems are triclinic, monoclinic, orthorhombic,
tetragonal, trigonal, hexagonal...
- α-spodumene is in the
monoclinic system, and the high-temperature β-spodumene
crystallizes in the
tetragonal system. α-spodumene
converts to β-spodumene...
-
Anatase is a
metastable mineral form of
titanium dioxide (TiO2) with a
tetragonal crystal structure.
Although colorless or
white when pure,
anatase in nature...
- it is
sometimes called "yellow lead ore". It
crystallizes in the
tetragonal system,
often occurring as stubby,
pyramidal or
tabular crystals. It also...
- mineral. It has the
chemical formula CuFeS2 and
crystallizes in the
tetragonal system. It has a br****y to
golden yellow color and a
hardness of 3.5 to 4...
- sinjarite, the
dihydrate of
calcium chloride,
crystallizes in the
tetragonal system.
Sinjarite is semitransparent, with pale pink color. Hydrophilite...
-
soluble in
water and
crystallizes from it as the
anhydrous salt in the
tetragonal system, as
elongated prisms or needles. It is
practically insoluble in ethanol...
- by
Gerhard vom Rath in 1873 led him to
refer the
crystals to the
tetragonal system.
Optical investigations have
since proved the
crystals to be still...
- deltahedra,
whose faces are
equilateral triangles.
Twisted trigonal,
tetragonal, and
hexagonal trapezohedra (with six, eight, and
twelve twisted congruent...
