Abstract

High-purity quartz is crucial in photovoltaics and semiconductors, but lattice Al impurities seriously limit its applications. A simple fluorine-free annealing-leaching process for removing lattice Al impurities from quartz is proposed. Pretreatment adjusts impurity distribution, reducing Al from 490.602 ppm to 67.109 ppm, and then annealing drives impurities to the surface. After annealing-leaching, Al content drops to 22.317 ppm, with a 66.75% removal rate. Compared to the original sample, over 95% of Al is removed. SEM, XRD, and XPS are used to analyze Al diffusion and removal mechanisms.
