The space-based glass samples were examined using neutrons, X-rays, and powerful microscopes and could be used in optical devices.
An international team of researchers has found that the next-generation optical device materials could be made in microgravity.
“The idea is to feel out the mechanisms behind space-based manufacturing, which can lead to materials that are not necessarily available on Earth,” said Jörg Neuefeind of ORNL. , unlike crystalline solids, has a random atomic structure. This unusual structure provides exceptional stability and adaptability, as seen in common things such as eyeglasses and fiber optics.
“We found that with containerless techniques, such as the levitator, we can create unconventional glasses in microgravity,” said JAXA’s Takehiko Ishikawa, who is an expert in this field. In their study of glass made in space versus on Earth, the research team utilized neutron and X-ray diffraction to evaluate the atomic structure of the glass samples.
Neutrons proved useful in identifying lighter elements, such as oxygen. On the other hand, X-rays assisted in revealing the distribution of heavy elements like neodymium and titanium within the glass.
