▎ 摘 要
NOVELTY - Apparatus comprises quartz tube (5), ventilation cavity body (1), metal substrate (4) and air cavity body (1), where air cavity body is a columnar structure. The metal substrate is provided with a metal base. The inner end of the metal substrate is fixedly connected with the air cavity body that is set with an air inlet (3). The cavity body is provided with pneuma multi-hole (2). The quartz tube is sleeved in the air cavity body. USE - Apparatus used for growing graphene. ADVANTAGE - The apparatus is simple in structure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an apparatus. Air cavity body (1) Ventilation cavity body (1) Pneuma multi-hole (2) Air inlet (3) Metal substrate (4) Quartz tube (5)
