Abstract
Scientists at Pacific Northwest National Laboratory (PNNL) determined how durable four-component glass is when aluminum atoms are replaced by boron atoms and vice versa. Researchers studied five glass samples (NeBO to NeB4) with different ratios of sodium, aluminum, and boron. The nuclear magnetic resonance spectrometry results were combined with flow-through dissolution experiments, which allowed the scientists to evaluate the relationship between the atomic structure and the rate of glass dissolution. Scientists found that water determines how fast the glass dissolves. Water breaks apart bonds between the aluminum and oxygen as well as silicon and oxygen under certain conditions. The spectrometry results were combined with flow-through dissolution experiments. The flow-through experiments allowed the scientists to evaluate the relationship between the atomic structure and the rate of glass dissolution.
