Abstract
This application provides a composite board, a preparation method, and a carrier. The composite board includes silicon dioxide and elemental silicon particles dispersed in the silicon dioxide. In this application, dispersing elemental silicon particles in silicon dioxide can increase the structural hardness of the composite board, reduce its porosity, form a dense composite board, and improve its overall performance when used as a carrier. This not only enables the reuse of silicon waste but also alleviates the problem of insufficient production of high-purity quartz materials.
