Quartz sand is a non-metallic mineral with silicon dioxide as its main component. It features high purity, great hardness, stable chemical properties and high-temperature resistance. It is formed by the weathering and sedimentation of quartzite, with abundant global reserves. After purification and processing, products of different particle sizes can be obtained. It has a wide range of applications, covering multiple fields such as building materials, glass manufacturing, chemical engineering, water treatment, and electronics, and is an indispensable basic raw material in industrial production.
