About the same time that Dr. Acheson Was experimentally producing Silicon Carbide, Charles P. Jacobs was attempting to produce a better grade of emery. He used a small electric furnace to extract the impurities of sand, iron, and titanium oxides from clay deposits rich in aluminum oxide. The result was a product that consisted of about 95percnt pure Aluminum Oxide (chemical symbol A1203).
