size of the process. in chromite processing and dressing industry, it is usually dozens of shaking table series or parallel installation to deal with excess tons. the quartz page: physical propertiesthe cause of this odd behavior is the crystalline nature of minerals. in a crystal the atoms are arranged in a regular and periodic manner that is specific for each mineral. the geometry of this arrangement of atoms is not only reflected in the symmetry properties of a crystal, but also in the isotropy or anisotropy of its physical properties. a substance that reacts differently depending on the direction of an external force is called anisotropic. different minerals are anisotropic to various degrees, and many of the physical properties of quartz show anisotropy. not all physical properties can show anisotropy, others can, but don 39;t alwaysthe following table gives an overview for the most important physical properties. the next 4 figures shall demonstrate schematically how the symmetry of the internal structure relates to anisotropy. the atoms of different elements are symbolized by circles of different size and color. the first example mineral composed of just 2 elements might a see full list on quartzpage.de light can be described as an oscillating electromagnetic field that propagates through space as a wave. a light wave has an electric and a magnetic field component. the wave planes of these components are oriented perpendicular to each other, as shown in fig. 1 for a single beam of light. the blue and orange sinus waves represent the electric and the magnetic fields, and the blue and orange arrows in the circle depict the orientation of the electric and magnetic wave planes. i should note that nothing in a ray of light actually moves up or down, or sideways. the sinus waves simply represent the direction of the electric and magnetic field vectors(which symbolize the direction and amount of a force) changing in time. the wave planes of light rays emitted from a lamp or from the sun are oriented randomly, and such light is called unpolarized, as shown in fig. 2. this is symbolized by a bunch of randomly oriented arrows (field vectors) in a circle. if all electric and all magnetic fiel see full list on quartzpage.de piezoelectricity many crystalline substances are made of electrically charged ions or molecules with an uneven distribution of electrical charges (inside the molecule, some atoms are more negatively and some more positively charged). the latter is the case in quartz: it is a macromolecular material that is built up by a network of sio4 tetrahedra, as the one shown in fig.8. in a sio bond the negative electrons get drawn more to the oxygen (such a bond is called polar, and oxygen is said to have a higher elec relative permittivity or dielectric number the value of rfor quartz is between 4.69 parallel to the aaxis and 5.06 parallel to the caxis, it is yet another anisotropic physical property. the dielectric number of quartz is not much different from that of glass (315), wood (35), or plastic (25). because it is chemically inert and mechanically very enduring, it is nevertheless an attractive dielectric, and is used, for example, to separate electrical circuit elements inside computer chips. see full list on quartzpage.de hardness hardness can be defined and measured in many ways. the most common unit is the value on the mohs scale. here a mineral 39;s hardness is estimated by comparing it with the hardness of 10 reference minerals that have been given the following mohs hardness values: a mineral with a higher mohs hardness value can scratch one of equal or lower value. so minerals of equal hardness do also scratch each other. quartz by definition has a mohs hardness of 7, cryptocrystalline quartz is a bit softer and giv fracture and cleavage pure macrocrystalline quartz shows a conchoidal fracture that is very similar to that of glass. massive quartz has an uneven fracture, and the same can be observed at the milky base of many crystals. in many cases the fracture is an irregular mixture of both uneven and conchoidal structures. as already mentioned, the luster of these fractures is vitreous/glassy to fatty. cryptocrystalline varieties fractures tend to be simply conchoidal, but more even. the luster of cryptocrystalline fracture tenacity quartz is elastic to some degree, of course not like a rubber band, but enough to be used in oscillators and as a membrane in ultrasonic loudspeakers. see full list on quartzpage.de on the other hand, quartz has a thermal expansion coefficient that is only slightly lower than that of ordinary glass and as you know no one in his right mind will serve hot tea in a wine glass. the thermal expansion coefficient is also anisotropic, and is smaller parallel to the c axis: if you heat up a crystal, it will get more elongated. for a single, isolated crystal this doesn 39;t matter too much, but in a crystal group the individuals will expand differently in different directions, which might induce considerable stress. the thermal conductivity of quartz is higher than that of glass, so overall it can take a bit more , but it 39;s still better to handle quartz crystals with care. in general, quartz feels cer than glass. the thermal conductivity is anisotropic and higher parallel to the caxis.

a section of his remarkable faden.itpage. see full list on quartzpage.de 2there are physical properties whose values by definition are independent of direction, and which have so called scalar units, for example the specific weight, temperature, or melting point of a substance. if a physical property or value includes information about a direction or is dependent on it, its unit is a vector, for example speed, acceleration, or electrical conductivity. 3that would be 3 principal axes in a threedimensional structure, of course, but the figure is only twodimensional. these principal axes correspond to the three crystallographic axes of a unit cell. 4light is neither a particle nor a wave, and describing it as a wave only means that we describe one aspect of its behavior and disregard those properties that make it appear as a particle. 5usually in conjunction with high energy radiation from radioactive sources which causes the generation of color centers. with the exception of
