Because there are repeated units, crystals have recognizable structures. Large crystals display flat regions (faces) and well-defined angles. Crystals with obvious flat faces are called euhedral crystals, while those lacking defined faces are called anhedral crystals. Crystals consisting of ordered array...
While found in all the colors of the rainbow, tourmaline actually occurs as clear crystals, which was given the nameachroite, from the Greek for “colorless.” Although among the rarest of tourmalines and usually found in very small crystals, this clear stone is rather inexpensive. Tourmaline ...

of an electron microscope. the images obtained in an electron microscope can be captured as electron micrographs with the help of specialized cameras. the study of metals and crystals became easy with the introduction of an electron microscope. stereo microscope a stereo microscope is defined as a...
The graph contains data of six different silicon suppliers between the years 2006 and early 2011 so that the individual fingerprint of the different metallurgical processes is averaged but a common picture on what is metallurgical refined solar silicon can be given. The highest level of metallurgical...
The common crystals are BaSO4 and PbSO4, AgC1 and AgBr, MgNH4PO4, 6H2O, and MgNH4AsO4, 6H2O, etc.. There are also some impurities with precipitation with different crystal structures, such as cubic NaCl and tetrahedral Ag2CrO4 crystal structure is different, also can produce mixed ...
invaded by groundwater. If the water is rich in minerals, they will precipitate out or crystallize in the same shape as the organism. The crystals fill and replace the organism, which dissolves away. If the organism decays slowly, then more crystals can form, providing a higher level of ...
It appears that the main way stones are formed in patients with hypercalciuria is by calcium oxalate crystals growing over Randall's plaque sites. In most stone phenotypes, overgrowths of the extremities of Bellini duct plugs have been observed; do these overgrowths le...
