Abstract: Quartz ceramics possess excellent properties such as low thermal expansion coefficient, good thermal stability, and low dielectric constant, making them key products in many structural and functional material fields. Based on the performance advantages and preparation process of quartz ceramic materials, this paper analyzes in detail the preparation technology of high−purity quartz powder and the key technologies in the preparation process of quartz ceramics. It summarizes the key factors and control principles for improving the performance of quartz ceramics and analyzes the application status of quartz ceramics in national strategic demand fields such as aerospace, float glass, electronics, metallurgy, and solar polysilicon. Aiming at the current status, development prospects, and existing problems of quartz ceramics application, corresponding research and design and development methods are proposed, and the future development direction and solutions of quartz ceramics are prospected.
