Chromium's main industrial use is as a pigment, but chromite, a naturally-occurring ore of chromium, is used extensively in the manufacture of magnesia chrome refractory bricks and refractory cements for furnaces and kilns. Sources directly from the ore contain iron, but the iron will oxidise to inert iron oxide in furnace conditions.
