It is polymorphous with the minerals Microcline and Sanidine.These three minerals form the Potassium Feldspar group.They are almost identical in physical properties, and it is sometimes impossible to distinguish one another without x-ray analysis. Products By Corundum Mineral Class. Diamonds are used to cut and polish other materials, such as glass and metals, because they are so hard. Ruby and Sapphire are scientifically the same mineral, but just differ in color. Minerals are used in much less obvious places. Corundum growth can be minimized by limiting available oxygen sources, ... WAM® AL products contain less than 0.3% silica, reducing the possibility of corundum formation as a result of metal interaction with the refractory lining. Proximal to the margin of the schistose rind, phlogopite and sapphirine are foliated parallel to the pod margin and to S 4 (Fig. Corundum is a crystalline form of aluminium oxide (Al 2 O 3) typically containing traces of iron, titanium, vanadium and chromium. Corundum in its pure state is colourless, but the presence of small amounts of impurities can impart a broad range of hues to the mineral. Some mineral specimens are relatively unpure and may contain other imbedded substances. Quartz is one of the most famous minerals on the earth.
