![]() A more fragile liquid will have a larger viscosity change with a given temperature change. The viscosity of the liquid glass changes considerably when it is cooled to the glass transition temperature. The results of the neutron experiments, published in Nature Communications, reveal a clear correlation between the medium-range atomic ring structure of a silicate glass and its liquid fragility. ![]() Neutron Scattering ExperimentsĬonducting neutron scattering experiments at the Department of Energy’s Oak Ridge National Laboratory, ORNL and Corning scientists discovered that as the number of smaller, less-stable atomic rings in a glass increases, the instability, or liquid fragility, of the glass also increases. This capability is important because the most widely used glass is silicate glass, which consists of different sizes of atomic rings connected in three dimensions. Recently, Corning researchers found that understanding the stability of the rings of atoms in glass materials can help them predict the performance of glass products. Given the stringent accuracy required in products like mobile phones and jet aircraft, it’s crucial that glass substrates remain unaltered in shape throughout the manufacturing process.Ĭorning Incorporated, a manufacturer of innovative glass, ceramics, and related materials, invests a tremendous amount of resources into studying the stability of different types of glass. Glass is increasingly utilized in various high-performance areas, covering consumer and industrial applications, military and aerospace electronics, as well as coatings and optics. This advance in understanding glass’s molecular dynamics aids in designing better glass products for high-performance applications. ![]() New research has uncovered the importance of atomic ring structures in glass, revealing how their stability influences glass’s performance and transition temperatures.
