Latest Patents

Schafer's latest patents include advancements in highly-coercive isometric iron oxides. One of his notable inventions is a process for the production of highly-coercive isometric iron oxide, which is useful in magnetic toners for electrostatic photocopying processes and magnetic printers. This process involves purifying brine used in electrolysis by the amalgam process. In this method, chlorine and alkali metal hydroxide are produced through electrolysis using calcium- and/or sulfate-containing crude salt. The calcium and/or sulfate contents introduced into the brine circuit by the crude salt are removed from the brine by precipitation of the double salt Na₂SO₄·CaSO₄. Small particles of glauberite may be introduced to the brine to initiate and accelerate precipitation.
