| Abstract Scope |
LionGlass is Penn State’s patent-pending group of phosphate-based glass compositions designed to reduce the glass industry’s growing carbon footprint. As glassmaking companies have started to reach out about this new environmentally friendly glass, it has become increasingly important to develop a method to determine if there are any compatibility issues between the glass and ceramic refractory materials. Laser Ablation Inductively Coupled Plasma Mass Spectroscopy (LA-ICP-MS) is an advanced way to determine how far the glass diffuses into the refractory material. With the data collected in LA-ICP-MS, diffusion coefficients and elemental activation barriers can be determined based on melting temperature. Results showed that an element’s activation barrier decreases with increasing atomic number. This surprising finding indicates that in this glass system, ion size is not the most important factor to be considered, and instead other factors such as molecular structure and charge play more into the diffusion process. |
