Sustainable ceramics without a kiln
Posted: Fri Jul 07, 2017 1:05 am
ETH material scientists have developed a new method of manufacturing ceramics that does not require the starting materials to be fired. Instead, they are compacted under high pressure at room temperature in a significantly more energy-efficient process.
The manufacture of cement, bricks, bathroom tiles and porcelain crockery normally requires a great deal of heat: a kiln is used to fire the ceramic materials at temperatures well in excess of 1,000°C. Now, material scientists from ETH Zurich have developed what seems at first glance to be an astonishingly simple method of manufacture that works at room temperature. The scientists used a calcium carbonate nanopowder as the starting material and instead of firing it, they added a small amount of water and then compacted it.
