Method for removing impurity barium in crystallization layer of waste quartz crucible, method for preparing high-purity quartz sand and high-purity quartz sand
The invention relates to a method for removing impurity barium in a crystallization layer of a waste quartz crucible, a method for preparing high-purity quartz sand and the high-purity quartz sand, and the method for removing impurity barium comprises the following steps: S1, separating the crystallization layer of the waste quartz crucible from a waste quartz crucible body to obtain the separated crystallization layer; s2, performing acid corrosion on the separated devitrification layer to obtain a corroded devitrification layer; the acid used in the acid corrosion is one of hydrochloric acid, sulfuric acid or hydrofluoric acid. According to the method, the crystallization layer on the surface of the waste quartz crucible is separated from the quartz crucible body, and then the crystallization layer is subjected to acid corrosion purification treatment, so that the impurity barium element in the crystallization layer of the waste quartz crucible can be fully removed.
本公开涉及一种废石英坩埚析晶层中杂质钡的去除方法及制备高纯石英砂的方法和高纯石英砂，所述杂质钡的去除方法包括如下步骤：S1：将废石英坩埚的析晶层与废石英坩埚本体进行分离，得到分离后的析晶层；S2：将分离后的析晶层进行酸腐蚀，得到腐蚀后的析晶层；所述酸腐蚀使用的酸为盐酸、硫酸或氢氟酸中的一种。本公开通过将废石英坩埚表面的析晶层与石英坩埚本体分离，再对析晶层进行酸腐蚀提纯处理，能将废石英坩埚析晶层中的杂质钡元素充分去除。
