Extraction of Aluminium - Hall (Electrolytic) Cell. The steel container is coated with carbon (graphite) and this is the negative electrode (cathode). Electrolysis of the alumina/cryolite solution gives aluminium at the cathode and oxygen at the anode. Al3+ + 3e- Al (aluminium metal at the (-)cathode) 2O2- - 4e- O2 (oxygen gas at the (+)anode) Aluminium is more dense than the…

Although aluminum oxide is certainly abrasive, it is also a skin irritant with a very questionably safety record. In any case, it is unquestionably unpleasant. If it gets into your eyes, it can scratch your cornea. If it gets into your ears, it can cause earaches. If it gets into your mouth, you will experience the unpleasant sensation of tooth enamel grinding away until it’s…

This final installment of the Abrasive Blasting Media series will discuss the merits of using both Steel Shot and Steel Grit for blasting. Both of these media types are produced from scrap steel which is melted, modified and then solidified into a generally round shape (Shot) or angular particles (Grit). Steel Shot produces a very smooth finish on the surface of metals. The…

Other hardness measurement numbers are found, such as, Brinell, Rockwell and Knoops. The Vickers hardness is up to about HV 500 about 1.04 times the Brinell hardness but most of the time hardness of the anodic oxide layer is measure by Vickers. Knoops hardness is almost identical with Vickers hardness except for the form of the diamond. In this testing method the diamond has…

Chemistry is used in everyday life, from making food to breathing air. Chemical reactions are what creates life, makes food into energy, and even what causes food to rot. When… you balance equations, you are learning the amount of elements used in the reactants, or found in the products. If you do not balance the equation, you will only know what you started with, and not the…
