| Research Abstract |
Instantaneous application of heat in hard glassy matrices induced by electromagnetic wave or radiation can trigger the formation of nano-sized balloon structure. The starting hard matrix was prepared by the sol-gel method since that method is advantageous to render a quite slight amount of low-molecular-weight species remain in the hardened matrix. In this process, low-molecular-weight species forms gaseous species that displace the surrounding hard matrix in an isotropic geometry. As a result of that, isotropic spherical voids are ubiquitously yielded. The most marked feature of those structures is that they tend to remain as small as 100 nm at most, which indicates the suppression of the mutual coalescence of those balloon-like structures. An auxiliary work is ongoing to process those materials with the nano-sized spherical voids into fine powder. The features of the obtained powders are preliminarily investigated form those kinematical behavior.
