一、实验用品六角螺栓(内直径2 cm左右)、铁板一块(内直径5cm左右)、镊子、滤纸、酒精灯、火柴、小刀、胶头滴管、金属钠。二、实验装置实验装置如图1所示:在三脚架上放一块圆形的薄铁片,并在铁片中心放上六角螺栓。把钠块放在六角螺栓中并用酒精灯加热铁片。用本实验装置还可以进行铝热反应实验,并能取得很好的实验效果~([1])。
First, the experimental supplies hexagonal bolts (diameter of about 2 cm), a piece of iron (inner diameter of about 5cm), tweezers, filter paper, alcohol lamp, matches, knife, plastic head dropper, sodium metal. Second, the experimental device Experimental device shown in Figure 1: Put a round thin iron plate on the tripod, and placed in the iron center hex bolts. Place the piece of sodium in the hexagon bolt and heat the iron piece with an alcohol lamp. With this experimental device can also carry out aluminum thermal reaction experiments, and can achieve good experimental results ~ ([1]).
