Aluminum is traded in competitive markets. Up to 1994‚ there were a handful of major firms that dominated the primary aluminum production. During 1980s‚ the top five private producers held more than one-third but less than one-half of the world’s production. However‚ by 1994‚ their share of the market dropped to one-third of the world’s production. Assume that no smelter has exited or entered the market since 1994 till 2010. Therefore current smelter is either still operating or idle. Also‚ technologies

RECYCLING ALUMINUM PURPOSE To determine the mass of a hydrated aluminum potassium sulfate salt in a sample of impure scrap aluminum from a common beverage can. The sample will be passed through a filter paper using a funnel‚ after being boiled on a hot plate in a fume hood and dissolved in a solution of potassium hydroxide to remove the impurities. By adding an excess of sulfuric acid and cooling the solution in an ice bath‚ the technique of vacuum filtration using a Buchner funnel will be employed

ZINC Zinc is one of the natural elements on the periodic table. It was discovered in Germany in 1746‚ by Andreas Marggraf. The name is from the German‚ ‘zinc’‚ which may be derived from Persian‚ which means ‘sing’. The element was known to the Romans but they rarely used it. When it was first used it was recognized. Zinc has a specification of metal made from ore or another material a process of distillation by electrolysis. The atomic number for zinc is 30. The mass number is 65.39 mass units

Pre-IB Science Research Paper Wood vs. Aluminum The decades old debate over aluminum vs. wood bats will probably exist as long as the choice is available. Baseball was played with wooden bats for a great number of years. In fact‚ even with the advancements in aluminum bats‚ it’s the professionals who use wood bats and the amateurs who use the all-mighty aluminum bats. So‚ the question is which is better‚ wood or aluminum? Aluminum bats are used in most Little Leagues because they are lighter

Usually‚ four types of materials are commonly used for actuators: * shape memory alloys‚ * piezoelectric ceramics‚ * magnetostrictive materials‚ * and electrorheological/magnetorheological fluids. Shape memory alloys are metals that‚ after having been deformed‚ revert back to their original shapes when temperature is changed. Piezoelectric ceramics expand and contract in response to an
