• Resumen

  • Ceramic membranes are artificial structures made up of minerals such as zirconium oxide, alumina, silicon carbide, titania and other functional materials used for their capacity to separate substances - especially aggressive acids and strong solvents used in chemical processing - while retaining their stability at extreme temperatures and pH levels. According to CoorsTek, its membrane can make hydrogen the cleanest and least expensive option for future automotive fueling - surpassing not only petrol and diesel but also electricity from the grid. Outlook for ceramic membranes While dense ceramic membranes for gas separation have received less attention to date than porous ceramic membranes for nanofiltration of liquids, typically used in wastewater treatment, the production of beverages, gas separation is a growing area of research and CoorsTek is not the only company pursuing this avenue of technical ceramics engineering. Dutch technology company Philips has a number of dense ceramic membrane products and R&D initiatives for gas separation and several universities across the world, including Rice University in Texas, US, have also published influential research on the subject.
