▎ 摘　　要

NOVELTY - A high-temperature reaction apparatus consists of a gas control unit, a powder control unit, a high-temperature reaction unit and a receiving unit. The gas control unit controls velocity of gas stream at inlet of high-temperature reaction unit. The powder control unit controls rate of powder entering into airflow. Gas-solid separation of reacted material is carried out at receiving unit and outlet of high-temperature reaction unit. USE - High-temperature reaction apparatus used in graphene material production system (claimed). ADVANTAGE - The high-temperature reaction apparatus enables manufacture of graphene material with high purity, without generation of side reactions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene material production system, which consists of the high-temperature reaction apparatus.
