LANXESS increases production volume of micronized iron oxide red pigments
LANXESS uses its proprietary Laux process to manufacture Bayferrox and Colortherm red pigments at its site in Krefeld-Uerdingen, Germany. Black pigments are heated up to 800 °C and oxidized to red pigment. Since the Copperas process, which was an alternative, is no longer used worldwide on a market-relevant scale, the much more environmentally friendly Laux process is the only production process applied for iron oxide red pigments that includes a calcination step at very high temperatures.
