Description
Molten silicate glasses flow or stiffen with their chemistry, and potassium oxide is a common lever. Mingwei Ma and co-authors simulated a melt of alumina, silica, and potassium oxide atom by atom in 2026, varying the potassium share. They tracked how the ions arrange, link, and move, looking for the structural story behind the melt's viscosity.
Silicon-oxygen units kept their stable four-sided shape throughout, untouched by the added potassium. But the angles linking those units first tightened, then loosened, as potassium rose, matching a viscosity that first climbed and then fell. Silicon's own movement followed the same arc. The simulations explain the flow behavior from the structure up.
