WebGraphite and the micas, for example, have cleavage planes parallel to their sheets (Figure 2.1.1), and halite has three cleavage planes parallel to the lattice directions (Figure 2.1.2). Quartz has no cleavage because it has equally strong Si–O bonds in all directions, and feldspar minerals have two cleavages at 90° to each other (Figure 2.3.6).

Crystal Habits and Forms of Minerals and Gems

Graphite is a crystalline form of the element carbon. It consists of stacked layers of graphene. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on large scale (300 kton/year, in 1989) for uses in pencils, lubricants, and electrodes. Under high pressures and temperatures it converts to diamond. It is a good (b… WebIn graphite, carbon atoms are contained in layers in a hexagonal pattern where the covalent bonds are shorter (and thus even stronger) than those of diamond. However, each layer is connected to the other with a longer and much weaker van der Waals bond. This gives graphite a single direction of cleavage, parallel to the basal pinacoid. http://webmineral.com/data/Graphite.shtml fitted tablecloth that looks like tile
