LionGlass is a phosphate-based glass developed at Penn State to reduce the glass industry's carbon footprint. As interest grows, understanding its compatibility with ceramic refractories is critical. Laser Ablation Inductively Coupled Plasma Mass Spectroscopy (LA-ICP-MS) measures glass diffusion into refractory materials, allowing calculation of diffusion coefficients and activation barriers. Results show that activation barriers decrease with increasing atomic number, suggesting ion size is less important than factors like molecular structure and charge in this system.
