The Savannah River National Lab has developed a novel class of materials for a variety of potentially new and exciting applications. This unique material is called porous wall, hollow glass microspheres. It consists of tiny glass microballoons that are smaller than the diameter of a human hair. The distinguishing characteristic of the SRNL glass microspheres is the interconnected porosity of their thin outer walls that can be produced on a scale of 100 A to 2,000 A. The porosity in these one-of-a-kind microspheres results in unique and desirable properties. ACerS is honored to be the first to published information on this startling and promising discovery and the captivating, never-before-seen photos of these glass microspheres in action.
