Highly Anisotropic Crystals (Materials Science of Minerals and Rocks),Used
Delivery time: 8-12 business days (International)
Anisotropy, i.e., the dependence of structure and properties on direction in space, is the most striking characteristic of crystals. Anisotropy is a result of the discrete nature of the crystal lattice, and it is the characteristic which distinguishes the crystalline state from another solid state of matter, the amorphous. The anisotropy of the structure and properties of crystals (this can be called their 'internal anisotropy') is also reflected in their external structure, i.e., morphology. The reflection is, however, nonlinear: properties such as mechanical hardness ... do not change strongly (typically several tens of percents, depending on direction) while the morphology ... : the linear sizes in different directions of individual crystals often differ by several multiples or even several orders of magnitude, depending on the symmetry of the crystalline lattice and/or of the crystal prehistory. The enhanced anisotropy of morphology is, as a rule, a result of growth kinetics of different crystalline faces; it reflects a nonlinear character of the kinetic laws of growth. This book is devoted to high morphological anisotropy. No strict classification of highlyanisotropic crystals exists. However some typical forms, or habits, can be singled out: first, whiskers (or needles, or fibers) as quasionedimensional crystals, and second, platelets as quasitwodimensional crystals.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
