Abstract
As an indispensable raw material for the semiconductor industry, high-purity quartz has great economic and strategic value. Since aluminum (Al) is a common impurity existing in quartz, removing Al from quartz is required for improving the quality of quartz. This article provides a quick and easy way to remove Al from the quartz. Utilizing the selective heating of microwave and the easy decomposition of NH4Cl during heating, the use of low-grade quartz sand and NH4Cl doping for microwave calcination combined with acid leaching reduced the Al content in a quartz sample from 738.8 ppm to 17.9 ppm, and the total impurity content was reduced from 1459 ppm to 85.4 ppm. According to the fitting results of the experimental data by the shrinking core model, it is determined that the leaching reaction is divided into two parts: external diffusion-controlled and product internal diffusion-controlled, thereby determining the existing state of Al in the quartz. The effects of the microwave treatment temperature, the doping reagent type and the amount on the Al removal rate were compared. Also, the differences between traditional calcination and microwave calcination were discussed.
