Crystal System Flashcards
Is a set of axes. This structure occurs from the intrinsic nature of the constituent particles to produce symmetric patterns.
CRYSTAL SYSTEM
All three axes are equal in length and all are perpendicular to one another
ISOMETRIC (CUBIC)
Two of the three axes are equal in length and all three axes are perpendicular to one another.
TETRAGONAL
All three axes are unequal in length and all are perpendicular to one another
ORTHORHOMBIC
Of four axes three are equal in length, are separated by equal angles and lie in the same plane. The fourth axis is perpendicular to the plane of the other three axes
HEXAGONAL
All three axes are unequal in length and none is perpendicular to another.
TRICLINIC
three axes are unequal in length and two axes are perpendicular to each other
MONOCLINIC
All three axes are of equal length and none of the axes is perpendicular to another but the crystal faces all have the same size and shape
