When those molecules are heated to high enough temperatures, the sand melts and loses its crystalline structure, and as it cools it gains an entirely different structure. Also called silica sand or quartz sand, silica is made of silicon dioxide (SiO 2 ). The processing repeats several times until the manufacturer creates a 99.9999% pure sample. Making silicone involves heating quartz sand to high temperatures to derive silicon, a natural element. New applications require a deep understanding of the tradeoffs for different types of DRAM. Photoresist is applied to areas where they want the silicon to remain, while the parts that must be removed are chemically etched. This attracts silicon from the crucible, creating what's known as a boule. Also known as doping, this process embeds atoms from different elements to improve conductivity. Silicone has quickly become the extremely popular safe alternative to toxic plastics due to its excellent characteristics such as high & low-temperature resistance, low chemical reactivity, water repel, resistance to UV, etc. Sand can be found on almost every country on Earth, blanketing deserts and lining coastlines around the world. Begin adding some sand not a lot, just enough to give it form. Silicon is reacted with methyl chloride (CH 3 Cl) over a copper catalyst, forming dimethyldichlorosilane ( [CH 3] 2 Si [Cl] 2 ). Let the test tube cool for five minutes. Use a Bunsen burner to heat 3 level teaspoons magnesium powder mixed with 3 level teaspoons clean, dry sharp sand (not sand from a beach because of salt contamination) in a test tube. To get the silicon, the oxygen is removed by mixing it with carbon and heating it in an electric arc furnace to temperatures beyond 2,000 degrees C. At those temperatures the carbon reacts with the oxygen, becoming carbon dioxide and leaving pure silicon in the bottom of the furnace. The majority of these entail mixing components at extremely high temperatures or distilling them. Muriatic acid is highly corrosive. Electronic-grade silicon still isn't perfect, because it has a polycrystalline structure.
