High purity quartz is an important raw material for the production of quartz glass and integrated circuit board, which is of great value and irreplaceable in the high-tech industry. With the continuous decrease of natural crystal resources, the research on high purity synthetic quartz has gaining more and more attention. This paper introduces the characteristics, synthesis technology and research status of high purity quartz in a comprehensive manner, besides, the important applications of high purity synthetic quartz are given in this paper. It is considered that the preparation of high purity quartz by liquid hydrolysis of SiCl4, a by-product of polycrystalline silicon production, is a technology that meets the requirements of sustainable development and has potential production value.
