一、实验用品六角螺帽(内直径2 cm左右)、铁板一块(5 cm×5cm)、药匙、坩埚钳、小铁锤、磁铁、打火机。氧化铁粉末、铝粉、氯酸钾(研细)、檀香线香一根(可用佛香替代)。二、实验装置实验装置如附图所示。三、实验操作和现象1.把六角螺帽放在一块方形铁板上(如附图中a所示)。如附图中b所示,将氧化铁粉末和铝粉按质量比3:1混合均匀后装入六角螺帽的孔内;再在铝热剂上方覆盖少量氯酸钾粉末,用药匙将氯酸钾与铝热剂略微混 First, the experimental supplies Hex nut (diameter of about 2 cm), a piece of iron (5 cm × 5cm), medicine spoon, crucible clamp, small hammer, magnet, lighter. Iron oxide powder, aluminum powder, potassium chlorate (research fine), a sandalwood incense line (available Buddha instead). Second, the experimental device Experimental device as shown in the figure. Third, the experimental operation and the phenomenon 1. The hexagonal nut on a square iron (as shown in a). As shown in the figure b, iron oxide powder and aluminum powder mass ratio of 3: 1 mixed into the hexagonal nut hole; then covered in the thermite over a small amount of potassium chlorate powder, the spoon with potassium chlorate and aluminum Heat agent slightly mixed
