Diamonds :: essays research papers

A infield is one of the two natural minerals that be produced from carbon. The other mineral is Graphite. Even though both of these minerals are produced from the alike(p) element ,carbon, they have totally contrastive characteristics. One of the closely self-explanatory difference is that baseball diamond is hard and Graphite is soft. The adamant is considered to be the most hardest substance found in nature. It scores a perfect x in hardness. Because of its hardness a tiny Diamond is used as a cutting and drilling tool in industry. Even the Greeks called the Diamond adamas which means unconquerable. Diamonds also conducts heat better than any other mineral .Diamonds come in several different color shades such as, yellow, down(p), green, or pink. One conclude why a Diamond has different colors is by means of the processes involving heat and radiation. Another reason is that 99.5% of a Diamond is Carbon and the rest are different trace elements. These 0.5% of elements a re the reason why a Diamond has different color shades. For example due north causes it to have a yellow tint , and Boron a blue shade. The pink color in some Diamonds are thought to be caused by de impressation of the atomic structure of the diamond crystal. A sodding(a) Diamond , which would be 100% carbon, is colorless Diamonds were created million years ago, when the reason was formed, the material experienced pressure of 5million times the atmosphere at ocean level and temperatures between 10001200degreesC. These conditions caused carbon in the layers inside the orbiter to crystallize into diamonds. The diamonds moved up to the earths surface through volcano eruptions. This is why many Diamond mines are near volcanoes. Diamonds devolve in two types of rock Kimberlite and Lamprolite. Diamonds are mostly found in South Africa, India, Brazil, Russia, Australia, and Arkansas. Right now about 100million carats are mined severally year. Today the largest cut Diamond in the worl d is the Cullian I at 530.2ct .The unit cell of a Diamond is cube. Five carbon atoms form tetrahedra at the cube corners , at the centers of for each one of the cube faces, and at foursome sites within the cube. The carbon atoms are located at the center of each tetrahedron . The carbon tetrahedra are covalently bonded, which explains why diamonds are extremely hard. The toughness of the Diamond comes from four planar directions of weakness , it is called octahedral cleavage .
