By Dr. Walter Borchardt-Ott (auth.)

As a self-study consultant, direction primer or educating relief, Borchardt-Ott's Crystallography is the right textbook for college kids and academics alike. in reality, it may be utilized by crystallographers, chemists, mineralogists, geologists and physicists. in keeping with the author's greater than 25 years of training adventure, the publication has various line drawings designed specially for the textual content and quite a few workouts - with ideas - on the finish of every bankruptcy. This second version is the interpretation of the 5th German version. the center of the booklet is firmly mounted in geometrical crystallography. it really is from the idea that of the gap lattice that symmetry operations, Bravais lattices, house teams and aspect teams are all built. The symmetry of molecules is defined together with the ensuing non-crystallographic aspect teams. Crystal types and the connection among element teams and actual homes are handled. a lot emphasis is put on the correspondence among aspect teams and house teams. The sections on crystal chemistry and X-ray diffraction are meant as an advent to those fields.

The values for topaz can now be calculated: The (110) face cuts a and b at unit length (Fig. 32). 1 (7), it is 90° - 62°08' = 27°52'. 529. From Fig. 26, 15' is the angle between (011) and b 001 \ OIl 8' \ 8" \ 8"\ \ \ \ \ \ 100 a b \ \ \ , Fig. 32. The all-positive octant of the topaz stereogram from Fig. 8 The Gnomonic and Orthographic Projections c (001), and from Tab. 1 (2), J'=43°39'. 954. 954 give the relative spacings (unit lengths) at which the unit face cuts the crystallographic axes a, band c.

The position of B or C with respect to the origin may be described by a vector r in terms of the lattice translations ii, b, and c: r = xii + yb +zc (see Fig. 3). The coordinates are yet another triple: x,y,z, where Os;x,y,z<1 for all positions within the unit cell. In our example, the atoms have the following coordinates: A: 0,0,0 This arrangement of atoms within a unit cell is called the basis. Lattice translations reproduce the atoms throughout the entire lattice (Fig. 1c), or: lattice + basis = crystal structure.

6 The Wulff Net The Wulff net is a device to enable measured crystal angles to be plotted readily as a stereographic projection. The Wulffnet is itselfthe stereographic projection of the grid of a conventional globe orientated so that the N'-S' direction lies in the plane of projection (Fig. 16). The N-S direction of the stereographic N' W' I- +++++H-+'T+++l a) b) Fig. 16a, b. The stereographic projection of the grid net of a globe (N'-S' 1- N-S) produces the Wulff net; the positions of the angular coordinates cf> (the azimuthal angle) and p (the pole distance) are indicated.
