▎ 摘　　要

NOVELTY - Preparation of flaky silicon dioxide involves using graphene oxide as template, polyvinyl pyrrolidone (pvp) as dispersant, and hydrolyzing tetraethyl orthosilicate (TEOS) on the surface of graphene oxide, producing silicon dioxide, and calcining for 2-6 hours at 700-1000 °C. USE - Preparation of flaky silicon dioxide (claimed) used for automobile coating, colored plastic, printing ink, ceramic product and cosmetics. ADVANTAGE - The method is simple, and provides flaky silicon dioxide having excellent appearance, adjustable diameter thickness ratio, powder uniformity, high purity and excellent dispersibility.
