Master of Science === Department of Chemical Engineering === James H. Edgar === I am a current employee for a chemical company that makes complex inorganic color pigments for a variety of uses. Some of the applications require iron as a base for a black color variant; but several require a purity level that precludes iron. One such product that cannot have iron in it is a computer based application that requires absolute purity of only the copper-chrome based powder with no impurities. This color is a powder that is primarily composed of copper and chrome and has the distinct advantage that it has little-to-no magnetic susceptibility. This makes it ideal for mixing with a form of acrylic for coating circuit boards and other computer applications as a magnetic field could severely damage circuits. Unfortunately, the presence of impurities (particularly ferromagnetic iron) can increase the magnetic susceptibility of the powder. We are here to discuss the search for a system to filter out such impurities.
