Water assists flash sintering to densify ceramic to 98% theoretical density in just 30 seconds

By April Gocha / September 19, 2017

Scientists at the University of California, San Diego have developed a method called water-assisted flash sintering that can densify powders to 98% of theoretical density in just 30 seconds. Their method takes place at room temperature and requires no external heating.
