South Africa‚ which accounts for 80% of the world production. As a member of the platinum group of elements‚ as well as of the group 10 of the periodic table of elements‚ platinum is generally non-reactive. It exhibits a remarkable resistance to corrosion‚ even at high temperatures‚ and as such is considered a noble metal. As a result‚ platinum is often found chemically uncombined as native platinum. Because it occurs naturally in the alluvial sands of various rivers‚ it was first used by pre-Columbian

Engineering Materials Week 9 12.11 Iron titanate forms in the ilmenite crystal structure that consists of an HCP arrangement of ions. (a). Which type of interstitial site will the ions occupy? Why? Since this ratio is between 0.414 and 0.732‚ the ions will occupy octahedral sites (b). Which type of interstitial site will the ions occupy? Why? Since this ratio is between 0.414 and 0.732‚ the ions will also occupy octahedral sites. (c). What fraction of the total tetrahedral sites will be occupied

Electrochemistry is a branch of chemistry that studies chemical reactions which take place in a solution at the interface of an electron conductor (a metal or a semiconductor) and an ionic conductor (the electrolyte)‚ and which involve electron transfer between the electrode and the electrolyte or species in solution. If a chemical reaction is driven by an external applied voltage‚ as in electrolysis‚ or if a voltage is created by a chemical reaction as in a battery‚ it is an electrochemical reaction

Engineering Materials Msc. Shaymaa Mahmood Introduction to Eng. Materials : Since the earliest days of the evolution of mankind ‚ the main distinguishing features between human begins and other mammals has been the ability to use and develop materials to satisfy our human requirements. Nowadays we use many types of materials‚ fashioned in many different ways‚ to satisfy our requirements for housing‚ heating‚ furniture‚ clothes‚ transportation‚ entertainment‚ medical care‚ defense and all the

Advantages: Sulfamic acid is the fastest de-scaler - It dissociates into hydroxonium ions more readily in aqueous solution than the others‚ therefore giving a greater concentration of atoms that are able to react with the calcium in lime scale. It is safe to use because it does not produce chlorine gas [5]‚ which can be toxic. Sulfamic acid also has a low volatility. Disadvantages: Sulfamic Acid can be an irritant to eyes or skin and is the most expensive of the de-scalers. Q2) How these de-scalers
