The crystal structure of Quartz is a very complicated. As a result of a changeover from alpha to beta Quartz, crystals form as hexagonal prisms with modified crystal faces. Click here for a detailed explanation on the crystal structure of Quartz. Transparency: Transparent to opaque: Specific Gravity: : Luster: Vitreous.

Rose quartz, translucent, usually turbid, very coarsegrained variety of the silica mineral quartz found in pegmatites. Rose quartz is valued for its pale to richpink colour, which may be due to titanium. It has been carved since early times and has been faceted to provide gems of good brilliance. Its milky aspect is attributed to tiny needlelike inclusions of rutile, which, when oriented ...

Genauere Definition, Unterscheidungen. Ein Kristall ist ein homogener Körper, denn er ist stofflich und physikalisch einheitlich. Aber viele physikalische Eigenschaften sind von der Raumrichtung abhängig, d. h. ein Kristall ist anisotrop.. Vor 1992 wurden Kristalle über ihre Periodizität definiert: In diesem Sinne ist ein Kristall dreidimensional periodisch aus gleichbleibenden ...

Quartz belongs to the trigonal crystal ideal crystal shape is a sixsided prism terminating with sixsided pyramids at each end. In nature quartz crystals are often twinned (with twin righthanded and lefthanded quartz crystals), distorted, or so intergrown with adjacent crystals of quartz or other minerals as to only show part of this shape, or to lack obvious crystal faces ...

Quartz crystals tend to grow a bit faster on the z faces than the r faces. The first guess would be that because of that the z faces are larger, but the opposite is true. Growth occurs perpendicular to a face, so if one face grows faster than another, then its surface actually shrinks. Thus the rfaces on quartz crystals are usually larger, and sometimes zfaces are completely absent ...

Quartz, widely distributed mineral of many varieties that consists primarily of silica, or silicon dioxide (SiO 2).Minor impurities such as lithium, sodium, potassium, and titanium may be present. Quartz has attracted attention from the earliest times; waterclear crystals were known to the ancient Greeks as krystallos—hence the name crystal, or more commonly rock crystal, applied to this ...

Quartz Crystals. by Merlin Emrys. Quartz is by far the most common and wellknown of all crystals. In addition to clear (rock crystal), amethyst, smoky, rutilated, and citrine are varieties. Rose quartz is also in this family, but it tends to form clumps rather than crystals. These crystals are found in almost every part of the world, with major deposits in Arkansas and Brazil.

Le quartz est un matériau anisotrope, et son comportement en fonction de la température dépend de l''angle de coupe du cristal. Cet angle de taille est choisi pour que la fréquence de résonance soit la plus stable possible en température. Par exemple un quartz taillé en diapason est généralement dimensionné pour avoir une courbe de température parabolique centrée sur 25 °C, de ...
